This Type-C 2S/3S BMS charging module is designed to charge and manage small lithium battery packs with nominal pack voltages of 8.4V (2S) and 12.6V (3S). It accepts a USB Type-C input and implements a charge current of up to 1.5A with a maximum power of 15W, providing a compact solution for safe and convenient battery charging.
Built as a battery management system (BMS), the module integrates essential charging control and protection functions to preserve battery health and prevent common failure modes. Key operational capabilities include charge management to follow the required charge voltage for 2S and 3S lithium packs, cell balancing to help maintain uniform cell voltages during charge, and protection against overcharge and over-discharge conditions. It also provides overcurrent and short-circuit protection to safeguard the pack and connected circuitry during abnormal events.
The module is suitable for integration into DIY battery projects, portable power packs, and repair or prototyping tasks where controlled charging and basic BMS protections are required. It is compact and intended for use with battery packs that match the stated cell counts and voltage levels. Ensure correct wiring, appropriate input power source, and compatibility with your specific battery chemistry and cell configuration before use.
