EGO Power+ ST1511T 15-Inch String Trimmer Review
The EGO Power+ ST1511T is a 15 inch cordless string trimmer built around the same 56 volt ARC Lithium battery platform EGO uses across its outdoor power equipment line. It sits in the middle of EGO's trimmer range, above the basic 12 inch kits and below the carbon fiber and telescopic models, which makes it the version most homeowners end up comparing against gas trimmers.
Quick answer
It is right for homeowners with a typical suburban yard who want gas-like trimming power without pull cords, mixed fuel, or engine maintenance, and who are willing to buy into the EGO 56V battery platform.

EGO Power+ ST1511T 15-Inch String Trimmer
ReviewedPros
- Brushes aside, the 56V motor delivers power that owners consistently compare to a light gas trimmer, which is unusual at this price point in cordless
- POWERLOAD head lets you reload line without disassembling the bump head, a genuine time saver over older two-piece heads
- Part of the EGO 56V platform, so the same battery runs EGO mowers, blowers, and edgers if you already own them
Cons
- This configuration is tool only, so the real cost is the trimmer plus a battery and charger if you are not already on the EGO platform
- At roughly 10 to 11 pounds with a battery installed it is heavier than many 40V competitors, which matters on long trimming sessions or for smaller users
The ST1511T pairs a 15 inch cutting swath with a 56V brushless motor and a bump feed head that reloads through EGO's POWERLOAD system. It uses the same ARC Lithium batteries as the rest of the EGO lineup, so it slots into an existing platform rather than starting a new one. Build quality is mostly plastic over an aluminum shaft, which keeps weight reasonable but is not commercial grade.
Real-World Notes
Owner feedback themes center on two things: power and battery runtime. Most users report the trimmer cuts through thick fescue and light weeds without bogging down, and that a 2.5Ah battery handles a typical suburban yard with charge left over, while a 5.0Ah pack covers larger properties. The recurring complaints are weight with a larger battery installed and the fact that the bump head, while easier to reload than most, still needs line that is not too thick or it will not feed cleanly. A smaller share of owners mention that the guard is on the small side, so more debris gets thrown than with trimmers that have a larger shield.

Who Should Consider Something Else
Skip this if you want a trimmer that includes a battery and charger in the box at this price, if you have a very large property where runtime per charge matters more than platform compatibility, or if you need a commercial duty unit for daily professional use. Homeowners with heavy brush or saplings should look at a brushcutter or a gas unit instead.
FAQs
Does the EGO ST1511T come with a battery and charger?
This configuration is tool only. You need a separate EGO 56V ARC Lithium battery and charger, or you can buy a kit version that bundles them, which is usually the better value if you are new to the platform.
What size trimmer line does the ST1511T take?
It accepts line up to 0.095 inch. EGO's own pre cut line and most standard 0.080 to 0.095 inch round line work, though very thick or serrated line can feed poorly in the POWERLOAD head.
How long does the battery last on a charge?
Runtime depends entirely on which EGO 56V battery you install. With a 2.5Ah pack most owners report enough runtime for a typical suburban yard, while a 5.0Ah or larger pack roughly doubles that. EGO does not publish a single runtime figure because it varies by battery and cutting conditions.
Is the EGO ST1511T good for edging?
It can edge along sidewalks and driveways when rotated, and EGO sells a separate edger attachment and dedicated edger models. It is not a substitute for a dedicated edger if clean, deep edges are a priority for you.
How does it compare to a gas trimmer?
Owners generally describe the power as close to a light gas trimmer without the fuel mixing, pull starting, and seasonal maintenance. It will not match a large displacement commercial gas unit for heavy brush, but for normal lawn trimming the gap is small.
Our verdict
The EGO Power+ ST1511T is one of the better cordless trimmers for a normal suburban yard, mainly because the 56V platform gives it real cutting power and the POWERLOAD head removes the most annoying part of string trimmer ownership. The catch is that this version is tool only, so the true cost depends on whether you already own EGO batteries. If you are already on the platform, it is an easy recommendation; if you are starting from zero, price out a kit before deciding.
