Momo Other Computer Components 3S BMS Battery Board

Momo's 3S BMS/PCM protection board is listed as Other Computer Components. It is for 12.6V / 10.8V lithium battery packs made with 18650, 26650 or polymer cells rated at 3.6V to 3.7V nominal. It protects against overcharge, over-discharge and short circuits, and manages balanced charging and discharging. The charging range is 12.6V to 13.6V, with a 20A continuous charge limit and a 30A maximum continuous discharge current. It can be used in screwdriver batteries and other portable power tools. Connect the pack at the labeled 0V, 4.2V, 8.4V and 12.6V terminals according to the wiring diagram; avoid intentional short circuits. For brush motors, the instructions call for a non-polarized capacitor rated above 25V, at 10µF to 100µF, across the motor leads to suppress reverse-voltage spikes. You can measure each series group's voltage to identify weak cells for replacement; regular monitoring helps maintain pack balance and service life.You may also like Momo Computer Components 4S 30A Board sku-17796770312.
