So let’s get going…..

1. Milwaukee 2725-21HD 18V M18 Cordless Electric String Trimmer

–Bovees Best Professional Cordless Weed Eater

From the veritable tool juggernaut, Milwaukee, comes this beast of a weed eater!!

Milwaukee are renowned for manufacturing top quality power tools and the 2725-21HD cordless string trimmer is no exception, leading the way in cordless trimmers it is right up there when it comes to the best battery powered weed eater.

Fitted with a Milwaukee® POWERSTATE™ motor means that this cordless string trimmer comes with all the advantages of a brushless motor to save you time and money with no compromise on power — full throttle is achieved within 1 second of pulling the trigger!

Brushless motors have many benefits over brushed motors including; more torque, more efficiency, longer lasting, less harmful emissions and less maintenance.

Having a high efficiency brushless motor also means that it is one of the quietest weed eaters on the market.

Having the motor mounted at the rear with a solid drive shaft design and gear box means this cordless string trimmer provides;

• superb cutting power
• excellent balance
• unquestionable durability

Then there’s the state-of-the-art battery system, the Milwaukee® REDLITHIUM™, which claims (and we have found no evidence to dispute this!) to have the longest run-time, the highest power output and longest battery life of any of the battery packs of cordless string trimmers on the market, a major consideration when deciding on the best cordless weed trimmer for you.

This advanced battery system combined with REDLINK PLUS™ Electronic Intelligence, provides unparalleled communication between the battery and the tool itself, which allows for the maximum possible levels of productivity, protection and performance compared to other battery powered models.

Those with other Milwaukee cordless tools, will also benefit from the fact that the battery for this cordless string trimmer is interchangeable between others with the M18 system.

With two speed settings on the variable trigger system, spinning the trimmer line at 4600 and 5800 rpm respectively, you also have control over the cutting power of your battery powered weed whacker.

This allows a great level of control over the trimmer head and what you are doing, and enables you to switch to high power for patches of tough weeds that you might otherwise need a brush cutter for, but resort to lower power (to save battery life) when trimming lightweight material e.g. grass.

The over mold grip handle on this cordless string trimmer is one of its best selling points.

It is probably the comfiest handle of all the string trimmers on our list. The extra support handle on the straight shaft offers better control and is also comfortable and soft while helping to absorb a lot of the vibration too.

It’s worth mentioning here that straight shaft trimmers are particularly good for using in tight spaces, compared to curved shaft trimmers.

The 16-inch cutting swathe is another notable feature, in fact, your weed eating productivity is increased by 30% over the other budget models of cordless string trimmer featured here, thereby cutting down on your work time.

The thickness of line used i.e. the line diameter, matches the power of the motor on this cordless electric string trimmer, so you will have less breakage of trimmer line and thereby save time and money replacing spools of trimmer line while still being able to tackle the toughest weeds.

Having said that, the full sized head stores more line than other models of cordless electric string trimmer, plus, changing your line with this tool is actually a nice easy, straightforward process.

Simply remove the spool and wind the string line around.

The head of this cordless electric string trimmer also has a reinforced metal bump knob to ensure a maximum working life of your battery powered weed whacker.

All in all if your budget allows then the Milwaukee 2725-21HD 18V M18 String Trimmer will not disappoint as the perfect complement to your lawnmower, and much more! Other string trimmers seriously struggle to compete with this battery operated weed eater…..

Pros:

• Milwaukee’s renowned high level of quality & service
• Rear Brushless Motor — multiple benefits
• Excellent battery system — save money on replacement batteries
• Variable speed motor — for power when you need it or extra battery life when you don’t
• Very quiet
• Excellent on-demand line feeding system.
• Over mold comfy handle grip — good for periods of extended use or those with arthritis
• Straight shaft – straight shaft trimmers are better for using in tight spaces
• 16” cutting swathe
• Suitable for both .08 AND .095 line thickness — thicker line = less breakage = time saving & money saving
• Battery & battery charger included
• 5-year warranty — peace of mind

Cons:

• Expensive — But you get what you pay for!!
• Does not convert to a lawn edger.

2. Greenworks 2101602 40V String Trimmer

–Bovees Best Budget Cordless Weed Eater

Greenworks are another big player in the gardening tool industry. Their range of tools are loved by a lot of the gardening community, and it’s easy to see why.

This 12-inch cutting weed eater is no different, running off Greenworks’ powerful 40v batteries, you should easily be able to get 40 minutes of usage out of the BST4000 cordless electric string trimmer.

Another great thing about the batteries for this cordless string trimmer is their potential for quick charging, one of the 40V batteries used to power this trimmer can be charged from 0-100 in just 30 minutes.

Weighing in at only just over 9 lbs means this battery string trimmer is nice and light and, in combination with the auxiliary handle, makes it an easy cordless trimmer to handle.

The adjustable flower guard on this cordless trimmer means that you can be sure not to obliterate your carefully nurtured flower beds while wielding your weed whacker.

Having a variable speed option, like the Milwaukee cordless trimmer, means that you can save battery charge when it isn’t required, by using less power when tackling grass and lightweight weeds with your battery powered string trimmer.

Every tool in Greenwork’s cordless range uses the same system of batteries.

As they also sell the tools on their own, click here for the tool only option, this can make purchasing Greenworks tools a lot cheaper than some of the competition.

As always, nothing is perfect, and this unit does have some small flaws.

The power of this trimmer means that even with Greenworks awesome batteries, you will run the battery down quite quickly compared to other battery powered weed trimmers.

However, if you have other small jobs to do while you wait for the battery to recharge, maybe a spell on the lawn mower, or if you have a second battery, then this is not an issue. It is still way more convenient than gas string trimmers.

Some reviews also report issues with the batteries degrading.

Also, it has a smaller cutting width than any of the other cordless models that we recommend in this article.

However, as a budget option it would certainly enhance your set of lawn care tools.

Pros:

• Light and comfortable to use
• Edge Guide — protects your flowers from accidental damage
• Variable Speed Control — saves on the life of the battery
• Auxiliary handle — gives better control
• Rapid charge batteries — allows you to do bigger areas with only a short break
• Tool also available without battery & battery charger — saves money for those with other Greenworks tools
• Two-year warranty on tool, three-year warranty on battery — peace of mind

Cons:

• Claims of battery degeneration problems
• Only 12 inch (30.48 cm) cutting width — takes longer to complete a job than with a 16-inch
• Only .065 trimmer line diameter — restricts the thickness of vegetation you can use it on

3. DeWalt DCST920P1 String Trimmer

–Bovees Best Domestic Cordless Weed Eater

Another eater in the high power bracket, DeWalt, produces some of the best tools on the planet.

They are a staple for both DIY use and commercial/trade use alike. Most commendably, they were the first ones to bring brushless motors into the mix.

This high-powered weed eater is designed to take on its gas powered brothers, and we have to say, it seems like it has done pretty well doing so.

The innovation and tricks that the DeWalt uses, bridge the gap excellently between the DCST920P1 and a gas powered alternative.

DeWalt batteries are second to none, their batteries charge rapidly, hold a great charge, and don’t degrade over time.

A fully charged DeWalt battery is going to give you the longest run time of any battery too.

At only 7.4 lbs, one of the main advantages to this unit is its low weight, coupled with a decent power output, which means you get a unit which is easy to maneuver while still being devastatingly effective. It definitely holds its own against gas powered string trimmers.

It creates hardly any noise, and you do not need to leave it idling like a gas-powered model.

It is also a very easy cordless weed trimmer to start, not needing a cumbersome pull cable as gas powered models do.

The ergonomics on this model are simply great too, the grip feels comfortable, and the weight is shifted just perfectly through the tool.  

Another massive plus to this unit is the low power setting, unlike lots of its competitors, the low power setting on the DeWalt is still extremely effective. This means you can save on the life of the battery, without the tool losing its cutting ability.

Light weeds and grass will never require you to move out of the low setting, so the battery loses less power.

On the low setting, you can often get up to 1 hour of use out of one fully charged battery, which places this unit at the top when it comes to the life of the battery.

If you already have DeWalt batteries, you will be able to buy just the bare unit at a great price too.

When it comes to tougher, harder to deal with tasks, you can up the power just by squeezing harder. This kicks the reliable motor into high power mode and will allow you to destroy anything in front of you, tackling jobs that you might otherwise need a brush cutter or a hedge trimmer for.

This model takes a 0.08 diameter line. Because of this line diameter, even upping the power does not risk line breakage. Moreover, the line is fed by a simple to use bump feed system.

Paired with the larger than average 13″ cutting area, jobs just get done faster with the DeWalt and it definitely fares well against gas weed eaters.

The downsides to this unit are tiny compared to the positives, but, according to reviews, it still seems to have a few.

The guard on the cutting head is not the most well designed and does not do the best job at preventing small stones from pinging off while cutting.

There are also some complaints that their batteries range in quality and how much power they provide.

Some users swear by the DeWalt battery system. Some people advise you to buy a brand-new battery as some that are supplied in the kits may be of lower quality.

However, overall, this is an excellent cordless tool and certainly a battery-powered weed eater that holds its own easily against gas powered models, even in a commercial setting and could even be considered overkill for DIY garden use. The perfect partner to your lawn mower.

Pros:

• Almost half the weight of the Milwaukee
• 0.08 Line thickness — less time-consuming breakage than with the Greenworks.065
• Bump feed system
• 13″ cutting swathe — as opposed to the Greenworks 12″
• Variable Speed trigger — allows you to switch between extra power and battery saving
• Auxiliary handle — gives better control
• Rapid charge batteries — allows you to do bigger areas with only a short break
• Tool also available without battery & battery charger — saves money for those with other DeWalt tools
• Three year warranty — peace of mind

Cons:

• No flower guard
• Only 13″ cutting path — takes longer to complete a job than with the Milwaukee 16″

4. WORX WG163 GT 3.0 20V PowerShare 12″ Battery Powered String Trimmer & Edger

A tool that performs way better than its price tag would suggest makes the Works WG163 GT a great buy.

As well as a great price tag, though, this is a machine packed with features and quality.

It is a dual trimmer/edger, which means you get two tools in one machine.

It has an extendable telescopic handle which is adjustable to suit your height specifications, a 12″ cutting width and an auto feed spool.

This battery weed eater utilizes Worx 20v batteries. These batteries perform surprisingly well across the board, they stand up in the face of the bigger brands like DeWalt and hold their head high.

Many people like to stick to one brand, as with DeWalt and Greenworks, Worx also reward you for doing so by allowing you to use their batteries across a range of their tools.

The build quality in this tool is also extremely good, the adjustable handle and plastic grip feel good in the hand, and it isn’t overly heavy.

It comes in the standard black and orange color scheme and looks as good as it performs.

With its innovative push-button command feed system you save money by controlling how much line is fed out, plus, changing the spools is extremely easy.

The rubberized internal wheels support the edger, which gives you smoother cleaner lines.

The spacer guard is adjustable to give you that little bit more precision when working close to the plants & flowers in your garden.

The head also tilts to 90 degrees for those tough to reach places.

There are a few downsides to this unit, however.

The wire spools on it are relatively small, and this means that you will be wearing down your lines pretty quickly.

This means over the long term, you may spend a little more time maintaining this unit, having said that, it still won’t be as long as one would have to spend on a gas string trimmer.

This is offset by the cheap cost of the unit to begin with, however.

Just something to consider.

Pros:

• All round very good value for money
• Rubberized wheels — accuracy and ease of use
• 2 in 1 trimmer / edger — saves buying a separate tool for edging
• Adjustable telescopic handle — helps you avoid back and shoulder pain
• Works with any Worx20v batteries you already own
• Adjustable flower guard — protects the precious blooms in your garden
• Head adjusts to 90 degrees
• Takes a trimmer line diameter of 0.065mm
• Automatic feed system

Cons:

• The line spools run out quickly due to their small size

5. Black+Decker LSTE523 Li 12″ Cordless Electric String Trimmer and Edger

Black and Decker has a reputation for quality when it comes to the tools they produce.

The LSTE532 is no different. Perhaps the most aesthetic tool on our list, the bold look of the LSTE523, gives it a professional feel.

Luckily that professional look isn’t just for show, and this really is a professional offering.

Built with a high-quality battery system, this tool is made to run all day.

The 3Ah system gives you a really long run time.

The power delivery is good, and although you won’t be able to fell trees with this bad boy, there isn’t much else that will be a problem.

The thing that really makes this unit stand out from the rest is the ridiculous amounts of features it is packed with.

With their EasyFeed system, all you need to do is push a button near to the trigger to make more spool extend.

Compared to a lot of “auto feed” systems, the EasyFeed system, just works, and works well.

There is also a Powerboost and Powercut setting on the unit which is guaranteed to deliver consistent power.

This allows you to turbocharge the cutting potential of your eater to tackle particularly stubborn areas.

If you are dealing with areas that you have left for too long, ones that are more jungle, than garden, the PowerBoost option will give you the muscle to deal with it.

As well as those amazing features, the LSTE523 comes with a lot of the great features that its competitors have.

You can adjust the shaft trimmers telescopic handle to match your height and reach, you can set the guard to protect the flower borders in your garden, it converts from trimmer to edger instantly and it has a 12″ cutting swath.

The unit does have a couple of downsides, however.

One being that the EasyFeeder feed spool, can cause you to get through spools quickly. Users are reporting that although the EasyFeeder is a great innovation, you just have to be careful, or you will be spending lots on new spools.

The second gripe is that when you are not using the PowerCommand buttons, the unit can feel a little under powered.

Whether that is because users are comparing the cutting ability to when the PowerCommand option is on or to other units, is unknown.

Pros:

• Feature-rich unit
• EasyFeed system works really well compared to bump feed systems
• PowerCommand buttons provide you with a quick boost of power for hard to deal with areas.
• 2 Speed controls allow you some flexibility
• Works with all B+D 20v batteries – so you can use the same battery for other tools.
• Telescopic shaft
• 2 in 1 Edger/Trimmer

Cons:

• EasyFeed system uses a lot of spools
• Can feel under-powered when not in PowerCommand mode
• Only 12 inch (30.48 cm) cutting width

6. Craftsman V20 Cordless String Trimmer / Edger (CMCST910M1)

Craftsman’s contribution to the battery-powered weed eater market is the v20 string trimmer. This is a dual line model, which makes light work of grass and weeds.

The speed provided by the v20 battery pack is pretty impressive.

So too is the motor which powers the spinner at a blistering 9000 rotations every minute.

This is one of the highest speeds reached by any battery-powered weed eater we have reviewed so far, making it a definite contender for best cordless trimmer.

The 13-inch cutting area isn’t as impressive as the Milwaukee or even the DeWalt, but it is still large enough to make dealing with even medium to large areas a breeze.

The fact that the unit only weighs 5.5 pounds (2.49 kg) adds to that ease.

You aren’t going to get as tired using the Craftsman as you would say with the Milwaukee.

The variable speed trigger is similar to the Dewalt, although it does not have the same responsive feedback, it still works really well. Paired with the high-speed motor, this is definitely not a tool to be underestimated.

The telescopic handle rotates 180 degrees and extends, and this allows you to set the tool however you want.

The two handles are well-designed and placed ergonomically.

All in all, the Craftsman is perhaps the most ergonomic tool on this list, so if you are looking for a tool that puts ease of use first, this may be your best bet.

The head of the unit has three different levels of tilt, making angled work a breeze.

The edge guard on this unit is also one of the better ones on the list, and you can cut in confidence, knowing very little is likely to ping off.

Craftsman has always made very durable tools, and they stand by this by offering a three-year warranty.

The downside to this cordless weed trimmer is the bump feeder for the spools.

Craftsman has tried to create an alternative to the auto feeders seen on most models on the market.

Unfortunately, it seems that the bump feeder does not quite hit the mark.

It works, but reviews would indicate that it isn’t an improvement over traditional auto feeders.

All in all, Craftsman has created a tool that excels in some areas but not in others.

Certainly, if you want a high-powered unit that weighs surprisingly little, this could be the best tool for you and would combine well with a mini lawnmower for a smaller sized garden.

Pros:

• High speed
• Brushless Motor
• Lightweight
• Great adjustability
• 13″ cutting width
• 3-Year warranty

Cons:

• The efficacy of the bump feed spool is questionable

7. EGO Power+ 15″ 56-Volt Lithium-ion Cordless Electric String Trimmer with 2.5Ah Battery & Charger

Like lots of their other tools, the EGO Power is pretty impressive.

Sporting the usual neon green-gray and plastic trim with a carbon fiber shaft, it just looks fantastic.

Aside from the awesome looks, the EGO Power is just as impressive when it comes to performance too, plus it comes at a great price, which is lowered to an even better price if you already own some EGO batteries.

It comes with a variable pressure trigger similar to the DeWalt, which gives the EGO Power similar control and feedback to a gas-powered model.

The motor stops when you let go of the trigger, too, which is a nice feature for those who are used to idling gas-powered shaft trimmer monsters.

The Powerload feeder, is one of the best on the market. Loading up your string into this feed spool system is amazingly simple.

All you do is feed one end into the trimmer head and hold it with some tension, then press the Powerload button, which will cause it to wind back into the head.

They knew what they were doing here, and they have managed to turn the worst part about using a trimmer, into something that is no longer a chore.

In terms of ergonomics, you can tell a lot of time has gone into the design and placement of the motor. The whole unit feels extremely well-balanced, and it isn’t too heavy or light at either end.

The power is great, too, as with all brushless motors, providing power that is constant and efficient, whether tackling tall grass or thick grass and on full power it will tackle thick brush as well.

Unfortunately, this is another of the battery powered trimmers featured here, where the stock guard needs to be improved.

You may get some fly off when using the EGO, which is a shame for a unit that scores so highly everywhere else.

Pros:

• Awesome feed spool system
• 15 inch (38.1 cm) cutting swath
• Great ergonomics
• Best aesthetic design on our list
• Works with all EGO batteries

Cons:

• Guard on the cutting head needs improving
• Batteries are expensive

Bovees Buyers Guide — Battery Powered Weed Eaters

Weight

One of the main reasons people swap from gas trimmer to battery powered trimmers, and immensely important, is the product’s weight. Not only are gas powered engines heavier than an electric motor but gas powered tools also have to incorporate a fuel tank and fuel which only add to the weight

One of the main selling points for battery-powered vs gas powered is that they are almost always lighter than their gas-powered brothers. All but one of the units on our list, for example, weigh under 10lbs compared to gas models which can weigh up to 20 lbs!

Weight is important, whether it’s a 10-minute job or a ten-day job, the less the unit weighs, the less tired you are going to get wielding the tool. For sure 20kg gas trimmers are going to tire you a lot quicker than a 5.3lbs (Black & Decker model) battery powered trimmer.

Not all battery-powered options are created equal, however, and many of the other offerings on the market are heavier than the ones we have suggested, if it’s a lightweight weed wacker you are specifically looking for, check out our article at that link.

The heavier models on the market will usually be using an older battery system. If this is the case, stay clear.

Not only do old nickel batteries, weigh more, but they also hold less charge and deteriorate much quicker than modern lithium-ion ones.

Power

One of the biggest reasons people are hesitant to adapt to battery-powered tools, as opposed to gas models or corded models (with the added nuisance of an extension cord!), is the outdated misconception that battery-powered devices aren’t as powerful.

For a long time, this was the case, but nowadays, thanks to the advancement in lithium-ion batteries and brushless motors, that gap is closing rapidly and there are less reasons to buy a gas weed eater.

If you are looking to buy a tool for anything less than the most strenuous of commercial use, we can now highly recommend going with battery power as opposed to gas powered string trimmers.

When it comes to battery power, a unit is normally measured in volts.

The most common are 20v battery voltage and 40v battery voltage.

40 volt models are the more powerful of the two, but they often come with a faster drain on battery.

If you are willing to buy a couple of spare batteries, you should probably go for a 40v model.

If you only need your weed eater occasionally or for a small job, stick to the 20v models. They are usually more than enough to get the job done.

Battery Life, Battery Size and Battery Capacity

Lithium-Ion batteries are the future, being smaller and lighter than Nickel Cadmium batteries (and light years ahead of lead acid batteries!)

We recommend everybody looking for cordless string trimmers, to only buy battery-operated devices that have swapped from Nickel Cadmium to the new system of rechargeable batteries i.e. lithium ion batteries.

Bear in mind, however, that not all Li-ion batteries are created equal.

The brands on our list: DeWalt, Black, and Decker, Ego are all known for being industry leaders in the innovation of lithium ion battery technology.

Their batteries are all great.

Lots of less reputable companies, however, use low-quality lithium-ion batteries, these degrade quickly and lose charge surprisingly quickly plus they are not so great if you are looking for more power.

When it comes to Li-ion battery life, you need to work out what lithium ion battery is going to be best for you and which cordless string trimmers come with that type of battery.

If you need a high-powered tool and a long-lasting battery, chances are you are going to have to buy multiple batteries so that you have at least one spare battery to re-load the battery pack.

DeWalt and Milwaukee have the best long-lasting battery design with a higher battery capacity, but they come at a higher price tag than their competitors.

Deciding the best cost x performance is going to be key in deciding what tool you choose.

If you do not need a Li-ion battery with a long life but need a tool with more power, then you can buy a kit that includes one battery and a tool with a 40v battery voltage or higher rating which will give you more power.

If you don’t need the most powerful tool or longest lasting battery, go for the more budget-friendly options on our list and follow the tips to extend battery life.

They still all perform amazingly in most tasks, the life of the battery may just be less impressive than the higher cost models. And after all, if you don’t actually need more power then why pay for more power?

Of course, another important factor will be whether you already own Li-ion batteries for any of the brands.

If you already have 3 EGO Power+ batteries, it makes sense to buy the EGO, etc.

Another thing to bear in mind is charge time. Some of the more innovative battery systems boast a 0-100% charge in under 30 minutes.

With the average rundown time being 45-60 minutes, this means you only need two batteries to keep constantly working without any down-time for battery charging.

Guard Quality

Most people do not particularly consider the quality of the guard design when it comes to choosing a battery operated weed eater.

However, when you have a tool spinning at over 5000 revolutions per minute, you do not want to be hit by a rogue pebble traveling at high speed!

As well as your own safety, if you are working with a weed wacker near your priceless mustang or a house with many windows, making sure the guard of your battery operated weed wacker is effective, is extremely important.

On the other hand, with a bigger, more protective guard, you also add weight to the unit.

This means that if you are focused on getting a weed eater that is as light as possible, you may have to trade off on the level of guard protection (maybe invest in some shin guards!).

If you don’t mind a bit of extra weight, you should probably opt for a unit with a better guard.

Another thing to bear in mind is that usually, with units that are 2 in 1 trimmers and edgers, the guards will usually be less effective in edge mode.

Line Feed Loading Mechanism

If you have been using weed eaters for a long time, you will know that the worst thing about them is usually trying to feed more string into their mechanism.

With gas-powered weed eaters, the line feed issue has always been a horrible, awkward task.

Luckily most battery-powered devices come with better innovations across the board and this applies to the feed loading mechanism of battery operated weed eaters too.

Automatic feeds are the new thing, replacing the old manual style in most of the new models of weed eater.

An automatic feed spool is a great feature which will allow you to spend a lot less time fiddling with the line and more time actually using the weed eater.

Some models have an automatic feed system that will extend line as it detects it is needed, which is awesome.

Others use a bump method where you bump the head onto a hard surface to force it to eject more line.

Some models still use the older system for setting line by hand, but you won’t find any models like that on our list.

So Which Battery Powered String Trimmer Is Right for Me?

As you can see, this isn’t a question that has a simple answer.

When it comes to choosing battery powered devices nowadays, you really have to figure out what you want from them.

Firstly we would advise you to figure out what you really need your battery string trimmer to do.

Figure out;

• How often you will need a powered weed eater?
• How long you will be using the tool for?
• Research the area you will be using it on and what other tools could overlap e.g. a hedge trimmer?
• Will your battery string trimmer need to deal with stubborn weeds, or is it just for grass?
• Think ahead — will your needs change in the medium to long term with regard to battery – operated tools?

Once you have worked out these things, you will be able to work out how much power you need your unit to have and what sort of battery type / power pack life would suit you best.

At that point you should be able to remove a lot of the potential options from our list of cordless weed eaters and in the end it will probably be down to a matter of price and what you feel you can compromise on.

If you can afford the Milwaukee 2725 -21HD then it’s a no-brainer, but if you are restricted by budget then there are plenty of other excellent cordless models of battery powered equipment to choose from.

Conclusion

With the innovation surrounding the lithium-ion battery and the brushless motor, battery-powered string trimmers are fighting to close the gap on performance between them and their gas-powered cousins or even corded electric string trimmers.

Choosing a battery-powered tool over gas powered trimmers or corded electric models is a great way to be a more environmentally friendly weed whacker, too, thanks to their low emissions and low noise production.

We are convinced that the string trimmer/cordless trimmer best suited to your needs is now only a click away!

Thanks for reading our reviews on the best cordless weed eaters!
