Product Details

3S 4S 11.1V 14.8V 4A Lithium-ion Battery Pack BMS

The circuit board is crafted using high-quality electronic components, ensuring stability and reliability. It is designed for use with 3S or 4S battery configurations, supporting 11.1V and 14.8V nominal voltages, and handling a current of 4A. This BMS is ideal for various applications requiring efficient and secure battery management.

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.
