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.

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.
