Product Details

This 15S 16S 40A Lithium ion Battery Protection Board For Battery Pack BMS manufactured by high quality Mos and IC imported . Keep your battery long cycle serivce life time.

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.
