22S 120A lipo lithium Polymer BMS/PCM/PCB battery protection circuit board for 22 Packs 18650 Li-ion Battery Cell with Balance with temperature switch
Note: this BMS with balance function. your battery need match, battery should have good consistency, if not sure, please use new brand battery.
this is version S, charge and discharge use same port.
if you want charge and discharge use the difference port, please select version D.
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, or load short circuit);
4) MOS transistor can control the battery charge and discharge;
5) low standby current consumption.
80A version, continuous work current: 80A over current: 160A
100A version, continuous work current: 100A over current: 200A
120A version, continuous work current: 120A over current: 240A
Parameter:
over charge: 4.25V
over discharge: 2.5V
charge voltage: 4.2V * 22 = 92.4V
continuous work current: 80/100/120A
over current: 160/200/240A
balance voltage: 4.2V
balance current: 50mA
size: 150mm * 102mm * 15mm
version S: charge and discharge use same port
charge: B+ and C-
discharge: B+ and C-
Wiring sequence: First solder line B- to battery negative, connect balance cable to battery(B1 B2 ... B22), insert the cable(socket), After check, then connect P-/ C- line, then look at the amount of the total voltage of the battery, if the voltage between C- and B+ equal the total voltage, it’s should be work properly.
Applications:
22S Li-ion18650,LiCoO2,LiMn2O4,Li(NiCoMn)O2 rechargeable batteries
22S 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.
