Anmbest Enhanced 4S 16.8V 40A 18650 Charger PCB BMS Protection

Anmbest Enhanced 4S 16.8V 40A 18650 Charger PCB BMS Protection Board Li-ion Lithium Battery Charger Lipo Cell Module for Drill Motor with Balancer
- High-accuracy voltage detection circuit, fine workmanship and durable.
- Highlight: Over-discharge protection, overcurrent protection, overcharge protection; High charge and discharge current; Compact size and lightweight.
- Conditions for Starting the Drill: To successful starting the drill requires three 15C-20C power batteries, or six 10C-15C power batteries (ordinary 18650 battery can not start the drill!! Recommended power battery models: SONY VTC4, VTC4A, VTC5A, VTC6). For connecting cables, use copper wire over 3 square millimeters, the shorter the better (can not use nickel plate!!!).
- MOS transistor can control the battery charge and discharge, low standby current consumption.
- Applications: Suitable for electric drill with starting current below 80A and power below 135W. Suitable for lithium batteries with nominal voltage of 3.7V and full voltage of 4.2V (including 18650, 26650, polymer lithium batteries, no size limit).

Detailed electrical parameters are shown in the picture
Suitable for: Â
1.Suitable for lithium batteries with nominal voltage of 3.7V and full voltage of 4.2V (including 18650, 26650, polymer lithium batteries, no size limit)
2.Suitable for electric drill with starting current below 80A and power below 135W .
Attention: Â
To successful starting the drill requires four 15C-20C power batteries, or eight 10C-15C power batteries (ordinary 18650 battery can not start the drill!! Recommended power battery models: SONY VTC4, VTC4A, VTC5A, VTC6).
When you wiring 0V, 4.2V, 8.4V, 12.6V, 16.8V, plese do it strictly according to the wiring diagram. Do not deliberately make it short circuit.
When using a brush motor type load, try to connect a non-polar capacitor (withstand voltage above 25V, capacity 10uF-100uF) in parallel with the positive and negative terminals of the motor to prevent the reverse spike voltage generated by the motor from interfering with the protection board or breakdown of the MOS tube.
When soldering the battery for the first time, do not connect any load or equipment to the output.
Do not mix the good battery and poor battery to use.
The internal resistance of 4 battery capacity are closer will be better.
