Greenworks 82V 16 in Cordless String Trimmer — 2.5Ah Battery, Brushless 1.5 kW

The Greenworks 82V 16" cordless string trimmer is a brushless, magnesium-built landscaping tool that delivers commercial-grade power and up to 2.5 miles of trimming per charge with the included 2.5Ah battery.

Designed for property owners and professional landscapers who want gas-level performance without fumes, this 82V trimmer uses a direct-drive brushless motor to send consistent torque to the spool. Its 1.1" diameter shaft and durable magnesium components expand the cutting arc and improve balance, while a compact battery pack provides long runtime. The unit weighs less than comparable gas tools and combines thoughtful ergonomics with a high-speed cutting head for precise edge work around yards and hardscape.

How powerful is this trimmer compared with gas models?

This Greenworks 82V model produces roughly 40% more cutting power than a typical 36cc gas string trimmer, thanks to a 1.5 kW commercial-grade brushless motor. The motor maintains stable speeds up to 5,700 RPM, delivering steady performance under load without the maintenance needs of a two-stroke engine.

• 1.5 kW direct-drive brushless motor for consistent torque
• Up to 5,700 RPM cutting speed for cleaner cuts
• Equivalent or better power than 36cc gas without emissions

What runtime and battery performance can I expect?

With the included 82V 2.5Ah battery (180 Wh), the trimmer can cover up to about 2.5 miles of line feed on a single charge under typical residential conditions. Variable speed control and a two-speed selector let you trade top power for longer runtime when needed, and the battery is a high-energy pack optimized for the 82V platform.

• Included 82V 2.5Ah battery rated at 180 Watt-hours
• Estimated trimming distance up to 2.5 miles per charge
• Variable speed trigger + 2-speed switch to conserve energy

How easy is it to feed line and maintain the head?

The Load N’ Go trimmer head is designed for fast reloading and can hold up to 34' of .095" line, reducing downtime during tasks. The direct-drive head eliminates belts and many wear items common to gas models, while the brushless motor reduces service intervals.

• Load N’ Go head accepts up to 34' of .095" trimmer line
• Direct drive design minimizes mechanical wear and maintenance
• Simple spool replacement keeps you working with minimal interruption

What makes the build and ergonomics suitable for extended use?

Greenworks combined a 1.1" diameter shaft with a magnesium housing to increase durability without adding unnecessary weight. The shaft diameter offers a wider cutting arc and better balance, while lightweight construction and an ergonomic trigger reduce fatigue over long jobs.

• Durable magnesium construction for lasting reliability
• 1.1" shaft improves cutting arc and handling balance
• Lightweight design for all-day usability and less strain

Who is this for: The Greenworks 82V 16" cordless string trimmer is ideal for homeowners with medium to large yards, landscape contractors seeking a zero-emission alternative to gas, and maintenance teams who need consistent cutting power with lower upkeep. It fits users who want gas-comparable performance, straightforward line loading, and longer cordless runtime from a single battery. Note: this 82V product is not compatible with Greenworks 80V batteries or chargers; use only 82V system components for optimal performance.
