Product Details

1.Provides protection for 4 series LiFePo 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 RS485 protocol

7.Support CAN protocol

8.Support bluetooth protocol

Notes

1) Wire connection strictly according to the drawing, do not intentionally short circuit.
2) Before charged, need to connect the cables first.
3) When the group of battery is connected in series, ensure that the voltage of each group of batteries voltage is the same. If not, fill each group of batteries separately before connecting them in series. In discharge tests, the group of cells with the fastest voltage drop is the differential cell.
