3S 20A Li-ion Lithium Battery 18650 Charger PCB BMS Protection Board 12.6V Cell 59x20x3.4mm Module

3 series 11.1V 12V 12.6V

(With recovery function-AUTO Recovery)

Scope of application: Nominal voltage of 3.6V, 3.7V lithium batteries (including 18650, 26650, polymer lithium batteries)

Product size: 59*20*3.4mm

Product weight: 4.3g

Charging voltage: 12.6V - 13.0V

Continuous discharge current (upper limit): 20A (if the heat dissipation environment is not good, please reduce the load current use)

Continuous charging current (upper limit): 10A

Standard version: suitable for drills with starting current below 40A and power below 65W.

Enhanced version: suitable for drills with starting current below 60A and power below 100W.

Note 1: Successful starting of the drill requires three 15C-20C power batteries, or six 10C-15C power batteries (ordinary 18650 can not start the drill!). ! !!!) .

Note 2: Strictly according to the diagram wiring 0V, 4.2V, 8.4V, 12.6V, do not intentionally short circuit.

Note 3: With a brush motor type load, you must connect a non-polarized capacitor (withstand voltage 25V or more, 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 breaking the MOS tube.

Note 4: When connecting 3 groups of batteries in series, please make sure the voltage of each group is the same, if not, please fill each group of batteries individually and then use them in series. When discharging test, the battery with faster voltage drop is the poor battery.
