BITOON 12-Inch Cordless Chainsaw Kit, 2×4.0Ah Batteries — Brushless, Auto-Oiler, Lightweight (Yellow)

The BITOON 12-inch cordless chainsaw is a compact, brushless electric saw kit that includes two 4.0Ah batteries, a charger, and auto-oiling for fast, low-fatigue pruning and light firewood cutting.

Built for homeowners, gardeners and small property managers who need a portable saw without the noise and fumes of gas models, this BITOON kit combines a high-efficiency brushless motor with two long‑run batteries and a tool-free chain tensioner. It’s designed to deliver quick cuts (up to 11 m/s chain speed) and repeatable performance: the 20V 4.0Ah battery system can make roughly 60 cuts of 4×4" wood per charge. Safety features such as an anti-kickback brake and automatic oiling keep the chain lubricated and the operator protected while you tackle pruning, storm cleanup, or splitting small rounds for firewood.

How quickly will this chainsaw cut through branches and small logs?

The BITOON brushless motor generates high chain speed to slice through 4-inch hardwood in just a few seconds, making repetitive cuts much faster than manual saws. Because the motor is brushless, it stays efficient and maintains performance longer under load.

• 1000W brushless motor for sustained power
• Chain speed up to 11 m/s for rapid cutting
• Estimated 4 seconds to cut through a 4" section
• Two 4.0Ah batteries for continuous work cycles

What safety and convenience features does it include?

Safety is addressed with an anti-kickback brake that stops the chain if a kickback occurs, reducing the risk of injury. Convenience is built into the design: an automatic oiler keeps the chain lubricated, and the tool-free tensioner lets you adjust or replace the chain quickly without extra tools.

• Anti-kickback brake cuts power during kickback
• Auto-oiling system supplies continuous chain lubrication
• Tool-free chain tensioner and bar lock knob for fast adjustments
• Lightweight 4.9 lb body reduces fatigue during extended use

How long will the batteries last and how is battery protection handled?

The BITOON 20V 4.0Ah batteries are designed to deliver multiple cuts per charge—roughly 60 standard 4×4" cuts—so you can complete typical yard jobs without pausing to recharge. Built-in low-voltage protection automatically shuts the tool off when voltage falls below 15V to protect the battery and motor from damage.

• Included two 4.0Ah batteries and charger — ready to use out of the box
• Estimated 60 cuts (4×4" each) per battery charge
• Automatic shutdown under 15V to prevent overload
• Charger included for quick turnaround between batteries

What accessories and support come with the kit?

The package contains everything needed to start cutting right away, plus spare chains and a convenient carrying bag. BITOON supplies a 12-month limited warranty and customer support for setup and troubleshooting.

• 12" chainsaw with 2 extra 12" replacement chains
• Two 4.0Ah batteries, charger, and an oil bottle for the auto-oiler
• Tool carrying bag, protective scabbard, and user manual
• 12-month limited warranty and customer support

Who is this for: The BITOON 12" cordless chainsaw is suited to homeowners, landscapers, and recreational users who need a lightweight, low-noise electric saw for pruning, storm cleanup, small firewood processing, and property maintenance. If you want gas-free operation, simple maintenance (no brushes to replace), and a kit that includes spare chains and batteries for extended work sessions, this model balances portability, power, and practical safety features.
