3S 40A 18650 - Lithium Battery Charger Protection Board for Drill Motor 11.1V 12.6V Module

Note 2: strictly according to map wiring 0V, 4.2V, 8.4V, 12.6V, do not deliberately short circuit.
Note 3: When the load of the motor brush is used, try to connect to the non- capacitor (withstand voltage above 25V, capacity 10uF-100uF) to the motor's positive and negative terminals to prevent the reverse spike from the motor. Break the MOS tube.
Note 4: 3 groups of batteries in series, please that the voltage of each group of batteries, if not the same, please fill each battery separately and then use in series. The The Discharge test, the voltage drop faster battery that group is poor battery.
For some of the poor basis of electronic customers to explain: balanced charge is only auxiliary functions, try to put a good battery and poor battery mixed together! 3 sets of battery capacity / resistance closer to the better! (2 good battery +1 Poor battery use effect = 3 poor battery use effect).
Charging voltage: 12.6V - 13.6V
