Product Details

10S 37V 15A lithium-ion battery protection board
This BMS protects 10 lithium batteries connected in series from overcharging, over-discharging, overcurrent, and short-circuit.
37V battery pack rated voltage, 42.5V battery pack full charge voltage, 36V battery pack rated voltage.
This board is not designed for high powered tools such as portable drills and alike.


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.
