Product Feature and Application

Our 1S 3.7V Li-ion BMS ensures efficient power management and protection against overcharging, over-discharging, overcurrent, and short circuits, safeguarding the battery and connected devices.

Product Details

1S 10A Li-ion battery bms with 10K NTC is used for li-ion battery without balancing function.

high-accuracy voltage detection circuit;terminal of the charger using high voltage device;

Built-in three-stage over-current detection circuit (over-current 1, over current, 2, load short circuit);
MOS transistor can control the battery charge and discharge;

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.
