Continuous Current: Discharge: 40A / Charge: 20A

Note 1: The successful start of the drill requires three 15C-20C power battery, or six 10C-15C power battery (ordinary 18650 can not start the drill).
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 brush motor is used, try to connect a non-polar 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 ensure that the voltage of each group of batteries, if not the same, please fill each battery separately and then use in series.
For some of the poor basis of electronic customers to explain: balanced charge is only auxiliary functions, try not 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).
