3S 20A Li-ion BMS Protection Board for 18650 Batteries 12.6V PCB Charging Module for LiPo Cells with Overload Protection for Drilling Motor
This BMS (Battery Management System) protection board is designed for 3S Li-ion and LiPo 18650 batteries operating at a voltage of 12.6 V. The module provides reliable protection against overcharging, overload, and short circuits, thereby ensuring a longer lifespan for the batteries and their safe usage. It is suitable for use in drilling motors, cordless tools, and other projects requiring stable power supply.
Thanks to its compact size of 59 × 20 × 3.4 mm and a lightweight of just 4.3 g, it is easy to install into battery packs. The board is designed for continuous discharge current of up to 20 A and charge current of up to 10 A, allowing reliable use even under higher loads. In environments with poor heat dissipation, it is recommended to reduce the current to maintain safety and stability.
