SEESII 40V 16 Inch & 12 Inch Cordless Electric Chainsaw 2×5.0Ah Batteries

The SEESII 40V Cordless Electric Chainsaw provides homeowners, gardeners, and property owners with a battery-powered cutting setup that eliminates gas mixing and direct exhaust emissions. It combines a 1600W brushless motor with two interchangeable cutting sizes, offering a clean alternative for trimming branches, cutting firewood, and cleaning up storm debris around the yard.

A notable feature is the 2-in-1 design that includes both a 12-inch and a 16-inch guide bar with matching chains. You can use the compact 12-inch setup for limb pruning in tighter spots, then switch to the 16-inch bar when handling thicker logs or small trees. The 1600W motor reaches chain speeds up to 42 FT/S, while a tool-free tension knob allows you to adjust chain tension or swap bars quickly without reaching for extra tools.

Power comes from two 18V 5.0Ah batteries that deliver up to 120 cuts or up to 60 minutes of runtime under tested conditions. The kit includes two fast chargers to help keep downtime low on larger properties. To manage maintenance, an automatic oiling system lubricates the chain continuously from a translucent 150ml oil tank that lets you check levels at a glance. For operation, it incorporates a chain brake, safety lock switch, protective hand guard, push-button starting, and a tested noise output as low as 75 dB.

While the dual-battery setup handles typical residential chores, runtime is capped at about 60 minutes under test conditions before needing a recharge. The tool also requires regular chain oil refills to keep the automatic oiler working properly during extended cutting sessions.

Verdict: The SEESII 40V Chainsaw is well suited for homeowners, cabin owners, and DIY gardeners who want the flexibility of two bar lengths and push-button electric starting without handling gas and pull cords.
