Product Details

LWS® 2S 7.4V 15A BMS includes advanced equalization functions that balance individual cells within the battery pack, promoting longer battery life and improving overall performance.

It protective functions of its predecessor, providing comprehensive safeguards against overcurrent, short circuit, over-temperature, and ensuring reliable battery charge and discharge protection.

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.
