3S 20A Li-Ion Lithium Battery 18650 Charger Pcb Bms Protection Board 11.1V 12V 12.6V Cell 59X20X3.4Mm Module

Description: Product name: 3-series 12.6V 20A lithium battery protection board (with self-recovery function-AUTO Recovery) Product size: 59*20*3.4mm 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) Continuous charging current (upper limit): 10A Standard version: Suitable for electric drills with starting current below 40A and power below 65W. Enhanced version: Suitable for electric drills with starting current below 60A and power below 100W. Scope of application: Lithium batteries with nominal voltage of 3.6V and 3.7V (including 18650, 26650, polymer lithium batteries) Note 1: Successfully starting the electric drill requires 3 15C-20C power batteries, or 6 10C-15C power batteries (ordinary 18650 cannot start the electric drill!!!). Note 2: Strictly follow the diagram to wire 0V, 4.2V, 8.4V, 12.6V, and do not intentionally short-circuit. Note 3: When there is a load such as a brush motor, a non-polar capacitor (withstand voltage of 25V or more, capacity 10uF-100uF) must be connected in parallel to 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 down the MOS tube. Note 4: When connecting 3 groups of batteries in series, please ensure that the voltage of each group of batteries is the same. If not, please fully charge each group of batteries separately and then use them in series. . . During the discharge test, the group of batteries with faster voltage drop is a bad battery. For some customers with poor electronic foundation, please explain: Never mix good batteries with bad batteries! The closer the capacity/internal resistance of the 3 groups of batteries, the better! (The effect of using 2 good batteries + 1 bad battery = the effect of using 3 bad batteries).
