3S 40A For Screwdriver 12V Li-Ion 18650 Bms Pcm Battery Protection Board Bms Pcm With Balance Liion Battery Cell Pack Module

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). 2. strictly according to map wiring 0V 4.2V 8.4V 12.6V 16.8V do not deliberately short circuit. 3. When the load of the brush motor is used try to connect a non-polar capacitor (with stand 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. 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. 5. The Discharge test the voltage drop faster battery that group is poor battery.
