2PCS 40A for Screwdriver 12V - 18650 Bms Battery Protection Board Pcm with Balance Liion Battery Cell Module

The successful of the drill requires three 15C-20C battery or six 10C-15C battery (ordinary 18650 can not the drill). Strictly according to map wiring 0V 4.2V 8.4V 12.6V 16.8V do not deliberately short circuit. When the load of the brush motor is used try to a non- capacitor (with stand voltage above 25V capacity 10uF-100uF) to the motor s positive and negative terminals to prevent the reverse from the motor. Break the MOS tube. Groups of batteries in series please the voltage of each group of batteries if not the same please fill each battery separately and then in series. The Discharge test the voltage drop faster battery group is poor battery.
