BMS Charging Protection Board 5S 18V 21V 20A Li-Ion Battery Module PCB for Power Tools Screwdriver Drill Overcharge and Short Circuit Protection
This protective BMS board is designed for 5S lithium batteries with an operating voltage of 18 V and a charging voltage of 21–24 V. It uses a special integrated circuit that monitors voltage, charging and discharging current, and ambient temperature of the cells in real-time. This ensures stable and safe protection against overcharging, excessive discharging, and short circuits, prolonging battery life and increasing safety during use.
The module is ideal for power tools, cordless drills, screwdrivers, and other devices that operate at 21 V. Its low energy consumption results in an operating current of approximately 25 µA and a standby current of only 6 µA, ensuring efficient operation and minimal losses. With compact dimensions of 46 × 40 × 3.6 mm, it easily fits into various battery assemblies.
