Защитная плата для литий-ионного аккумулятора 18650

Notice:
Product details may vary due to different production batches. If you understand the difference, please buy carefully.
Please allow 1-5mm difference due to manual measurement.
Item colors may appear slightly different on computer monitors because monitors are not calibrated the same

1: The successful start of the drill requires 3 15C-20C power batteries, or 6 10C-15C power batteries (ordinary 18650 cannot start the drill!!).For 0V and 12.6V cables, use more than 3mm2 copper wire (nickel plates cannot be used!!)!
2: Strictly follow the map wiring 0V, 4.2V, 8.4V, 12.6V, 16.8V, do not deliberately short-circuit.
3: When using a load with a brushed motor, please try to connect a non-polar capacitor (withstand voltage above 25V, capacity 10uF-100uF) to the positive and negative terminals of the motor to prevent reverse spikes of the motor. Break the MOS tube.
4: When using 4 groups of batteries in series, please ensure that the voltages of each group of batteries are different, if they are not the same, please fill each battery separately, and then use in series. During the discharge test, the battery pack cell voltage drops faster.


Balanced charging is just an auxiliary function, try not to mix good batteries with bad batteries! The closer the capacity/resistance of the 3 groups of batteries is, the better! (2 batteries are good + 1 battery is used badly = 3 batteries are used badly).
