8S 120A 25.6V LiFePO4 BMS/PCM/PCB battery protection circuit board for 8 Packs 18650 Battery Cell with balance function, with Temperature switch.
60A version:continuous work current 60A, over current 60*2=120A
80A version:continuous work current 80A, over current 80*2=160A
100A version: continuous work current 100A, over current 100*2=200A
120A version: continuous work current 120A, over current 120*2=240A
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.
120A version Parameter:
over charge: 3.75V
over discharge: 2.1V
charge voltage: 3.65V * 8 = 29.2V
continuous work current: 120A
over current: 240A
balance voltage: 3.6V
balance current: 50mA
size: 150mm * 102mm * 15mm
version S: charge and discharge use same port
charge: B+ and C-
discharge: B+ and C-
do not use P-, P- is for difference port.
Wiring sequence: First solder line B- to battery negative, connect balance cable to battery(B1 B2 ... B8), insert the 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.
step 1: connect battery, check carefully
step 2: plug the balance cable.
Applications:
8S 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.
