Description

Features: Engineered with double IC for precise voltages monitoring and multi layered protections (overheating, overvoltage, undervoltage) With optimal safety and extended life for 18V BL1850B/BL1840B batteries. Featuring a high 15A discharge rate, 60A continuous current tolerance, and advanced safeguards against short circuits, maintaining stable performances. Perfect for construction site or repair workshops, the board's low voltages shutdown mechanism prevents battery damage during extended operating. Direct replacement for BL1850B/BL1840B packs, this green PCB requires cell voltages synchronization before installation to ensuring seamlessly compatibility with 18V battery systems.
