DCST970X1 FLEXVOLT 60V MAX Lithium-Ion Brushless 15" String Trimmer, Two Speed (3.0AH)
Bottom Line
Most electric weed eaters end up being somewhere in the 20V range, but this 60V lithium-ion brushless weed eater packs enough power to cut through the tough stuff.
About
The brushless motor means it’s not going to heat up too quickly, so it runs cooler and smoother, allowing you to use it for longer. 60V batteries take a lot longer to run out, making this perfect for mild commercial use if you landscape. There are also two speeds to choose from, which will help you utilize the 15” string to the best of your ability. That wide range handles a larger area space than your standard electric weed eater but also includes a deflector with enough width to ensure nothing’s going to come firing at you. You should be wearing goggles, but the added guard is still helpful. Lastly, there’s an ergonomic coated ring grip along the handle, giving you more control over your cutting style and precision.

It’s hard to beat this one - except on the price. While it’s slightly cheaper than the contender model we’ve selected, you have to understand that this is definitely an investment. Dewalt doesn’t want you to feel like you’re left in the dark, which is why they put a three year comprehensive warranty on this weed eater, which is more than you’re going to find with Greenworks or Black and Decker models in the same price range. The power is excellent, the battery life is phenomenal and that’s all there is to it.

DCST920P1 Brushless Trimmer
Bottom Line
This budget friendly option doesn’t sacrifice power. You get a high-quality, low noise brushless motor to give you more control over your yard, running off a 5.0 Ah power source.
About
If you’ve ever owned a self-feeding weed eater, you know that they often don’t work well after a bit of grass has gotten on it. This features a bump feed for the string, which is far more reliable. And let’s talk about that string. You get a 13” cutting path, helping you cover more ground and edge the yard with complete confidence. Most weed eaters make the mistake of not having a large enough path, making them take ages to use. Grab your 20V battery, which charges super fast, pop it in and get ready to conquer every aspect of your yard.
Editor's insights
You’ll notice that our picks gradually went down from their 60V to a 40, then this 20 model. There’s nothing wrong with a 20V battery, but it’s not going to last as long as the others. That’s partially because while you have a powerful 5.0 Ah power source, the battery capacity is lower than it should be, so it sacrifices a lot of energy towards this. I recommend getting a second battery to keep handy. Either way, you’ll get up to 6,000 RPM, which is commercial grade power. It gets the job done and maintains a wide cutting path, but keep an eye on that battery.

DCST990H1 40V MAX 6.0 Ah Lithium Ion XR String Trimmer
Bottom Line
With similar attributes to our top pick, Dewalt’s 40V weed eater offers a little more physical power at a little more cost.
About
First of all, your 40V batteries are still double the capacity of most batteries on the market, so you have that going for you. Dewalt also ensured that the ring grip on the handle is still there, which provides mastery and dominance over your tool, letting you keep things nice and tidy in the yard. There’s also a super simple operation to get things moving. But let’s talk about the motor. The top pick had a 3.0 Ah motor, and this has a 6.0: double the power, so you can cut through even more underbrush, thick weeds and even bamboo. You get their XR string for a wider reach. In fact, the only downside is that the guard is relatively small. You should always have a good pair of goggles while using a weed eater, especially one as powerful as this.
Editor's insights
Considering most electric lawn equipment is loud as can be, I’m happy to say that this is actually very quiet in comparison. There’s no pull cord and there’s a strong grip. However, the downsides come out when you get to Dewalt’s promise of low maintenance. You won’t have to take apart the chassis every three months or anything like that, but don’t let that promise prevent you from checking for maintenance. No weed eater is all-powerful. The multi-speed function is great, but beware: it’s super sensitive, so finding the perfect mode is going to require precision.
