Product Details

1S 4A 3.7V BMS is a smart and efficient battery management system designed for single-cell lithium-ion batteries. It communicates with a device host and can display real-time battery data on an LCD or a mobile phone. Ensure safety and optimal performance for your 3.7V battery applications with this BMS.

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.
