BMS 3 strings 12.6V 20A lithium battery protection board (with recovery function - AUTO Recovery)

Parameters:
Scope of application: lithium batteries with a nominal voltage of 3.6V and 3.7V (including 18650, 26650, and 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)
Continuous charging current (upper limit): 10A
Enhanced version: suitable for electric drills with starting current below 60A and power below 100W.

Precautions:
1: Three 15C-20C power batteries, or six 10C-15C power batteries are required to successfully start the electric drill (ordinary 18650 cannot start the electric drill!!!); If it cannot be started, please contact customer service to tell you the solution.

2: Wiring 0V, 4.2V, 8.4V, 12.6V strictly according to the diagram, do not intentionally short circuit.

3: When there is a load with a brush motor, a capacitor (10uF-1000uF) must be connected in parallel to 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 tube.

4: When connecting 3 sets of batteries in series, please ensure that the voltage of each set of batteries is the same, if not, please charge each set of batteries separately and then use them in series! ! !

5: During the discharge test, the group of batteries whose voltage drops faster is a poor battery.

Explain to some customers with poor electronic foundation: don't use good batteries and bad batteries together!! ! The closer the capacity/internal resistance of the 3 groups of batteries is, the better! (The use effect of 2 good batteries + 1 bad battery = the use effect of 3 bad batteries).
