Function Details
1. Provides protection for 4 series LiFePO4 battery pack
2. Provides protections in charging and discharging
3. Processes the balance between cells smartly, the current of it can be set freely by external components.
4. Deals with over-current and short-circuit protection with circuit itself
5. Protect an electrical circuit from damage caused by over current/ over load or short circuit
6. Support SMBUS protocol
7. Support Bluetooth protocol
Wiring precautions
First connect the B- of the BMS to the total negative terminal of the battery pack, Wiring B-, B1, B2... B+, output charge and discharge negative electrode connected to P-, charge and discharge positive electrode connected to the total positive electrode, please wire connection strictly according to the drawing and use thick cable to connect with P+/ C+/ B+ and P-/ C-
