5S 10A 21V lipo lithium Polymer BMS/PCM/PCB battery protection circuit board for 5 Packs 18650 Li-ion Battery Cell
Note: if your application is high power electric tools, like drill or screwdriver, please do not buy, this PCM just 10A, electric&x27;s Inrush current is too high, this PCM will enter over current protect status, then cut off.
Features:
1) high-accuracy voltage detection circuit;
2) terminal of the charger using high voltage device;
3) Built-in three-stage over-current detection circuit (over-current 1, over-current 2, load short circuit);
4) MOS transistor can control the battery charge and discharge;
5) low standby current consumption.
Parameter:
over charge: 4.25V
over discharge: 2.5V
charge voltage: 4.2 V * 5 = 21V
continuous work current: 10A
over current: 35A
size: 63mm * 36mm * 8mm

Applications:
5S Li-ion18650,LiCoO2,LiMn2O4,Li(NiCoMn)O2 rechargeable batteries
5S Lipo rechargeable batteries
Notice:
1. Please pay attention to the use condition of input and output voltage and load current , make the protective plate within the power consumption of no more than specification allows power consumption;
2. Connect the battery will happen cannot discharge status, in this case, connect the charge can be restored to normal working state;
3.If a set of batteries with over-discharge and over-charge cells, the bms cannot be charge and discharge.
