2S 3A 18650 BMS Li-ion Battery Charger Protection Board

The 2S 3A 18650 BMS Li-ion Battery Charger Protection Module is a versatile and essential component for managing and protecting your lithium-ion battery packs. Whether you’re building a custom power bank, portable device, or any other project that requires safe and efficient battery charging, this module offers several key usually features.

Features:

1. Dual-Series (2S) Configuration: The module is designed for 2-series (2S) lithium-ion battery packs. It allows you to connect two 18650 cells in series, effectively doubling the voltage while maintaining a balanced charge.
   
2. Current Rating - 3A: This BMS supports a maximum charging current of 3A. It’s suitable for applications where moderate charging speed is sufficient.
   
3. Battery Management System (BMS): The integrated BMS ensures the following:
   Balanced Charging: The module monitors individual cell voltages and ensures that both cells are charged evenly.
   Overcharge Protection: It prevents overcharging by cutting off the charging current when the cells reach their maximum voltage.
   Overcurrent Protection: If the charging current exceeds the specified limit, the Short Circuit Protection: In case of a short circuit, the BMS disconnects the battery from the load.
   
4. Compact Design: The module’s compact size makes it easy to integrate into your project. It features solder pads for connecting the battery cells, input, and output.
   
5. LED Indicators: Some variants include LED indicators that show the charging status (e.g., red for charging, green for fully charged).
   
6. Widely Used: The 2S 3A BMS is commonly used in applications such as power banks, flashlights, RC models, and portable electronics.
   Remember to follow proper safety precautions when working with lithium-ion batteries. Always use genuine 18650 cells and ensure proper insulation to prevent short circuits.
