2pcs 3S/4S 40A 18650 26650 Lithium Batteries Charger BMS Protections Board for Drill Motor 3.6V,3.7V Lipo Cell Battery

Features:
Multiple Protections: Over-discharge protection, overcurrent protection, overcharge protection; High charge and discharge current
MOS transistor can control the battery charge and discharge, low standby current consumption.
Suitable for lithium batteries with nominal voltage of 3.6V,3.7V (including 18650, 26650, polymer lithium batteries).Besides, it can use for electric drill with starting current below 80A and power below 135W.
Note1:Successfully starting the drill requires 4pcs 15C-20C power batteries or 8pcs 10C-15C power batteries (regular 18650 cannot start the drill).
2:Strictly follow the wiring diagram for 0V, 4.2V, 8.4V, 12.6V, and 16.8V, and do not short circuit.
3: When carrying loads with brush motors, try to parallel a nonpolarized capacitor (with withstand voltage of 25V or more and a capacity of 10uF-100uF) at the positive and negative terminals of the motor to prevent the reverse peak voltage generated by the motor from interfering with the protection board or breaking down the MOS transistor.
