4S 60A LiFePO4 BMS/PCM/PCB battery protection circuit board for 4 Packs 18650 Battery Cell with balance function, with temperature sensor.
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.
Parameter:
over charge: 3.75V
over discharge: 2.1V
charge voltage: 3.65V * 4 = 14.6V
continuous work current: 60A
over current: 120A
balance voltage: 3.6V
balance current: 50mA
size: 112mm * 55mm * 10mm
?
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 ... B4), insert the balance cable(socket), After check, then connect 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:
4S lifepo4 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.
