4X 3S 40A for Screwdriver 12V Li-Ion 18650 Bms Pcm Protection Board Bms Pcm with Balance Liion Cell Pack
- 1.The successful start of the drill requires three 15C-20C , or six 10C-15C (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 separately and then use in series.5. The Discharge test, the voltage drop faster that group is poor .
