3S Li-ion 40A BMS Board with Charge Balancing Function

Nominal Voltage: 11.1V
Rds (on): 3mR
Continous Current: 40A
Over Current Protection: 80A

Typical Performance (per cell)
Overcharge Protection Voltage: 4.3V
Balance Charging Start Voltage: 4.17-4.23V
Balance Current: 100mA
Balance Charging Current: 1.72W
Over-Charge Recovery Voltage: 4.15V
Over Discharge Protection: 2.5V

Reminder:
Always put a heavy capacitor (>100uF/25VDC) across the BMS output terminals if you are using the battery to power brush DC motors. This will prevent the motor back-emf from damaging your BMS.
