1. First connect the B- of the BMS to the total negative pole of the battery pack;
2.The cable starts from the thin black one connecting B-, the second red wire connects the positive pole of the first string of batteries, and the next string is connected in turn to positive pole of the battery,B-,B1,B2……B3; then insert the cable into the BMS;
(The maximum number of strings is 3-4 strings, the example picture is 15 strings) (Please weld the wires in order and avoid pseudo solder joints.)3. Collegare il caricabatterie C-/Carico P- con BMS C-/P- (Utilizzare cavi di dimensioni maggiori)
4. Collegare il polo positivo: Caricabatterie C+/Carico P+ con pacco batteria B+ (Utilizzare cavi di dimensioni maggiori) .

3. FAQ
|
Q: How many Ampere protection circuit boards should choose? UN: It depends on your load power such as electric motor power please contact the sales or technical support before buying. Q: What is the distinction between same port wiring and different port wiring? UN: The cathode of charger and load is different for different port wiring , the cathode of charger and load is same for same port wiring and the charging current is equal to the discharge current. Q: What is the distinction between balance and unbalance function? UN: Equilibrium function is that high voltage cells will be discharged with resistor, waiting for the low voltage cells , to achieve the each cell voltage is consistent , to improve the battery performance for the whole group. Q: Do you have Minimum Order Requirement (MOQ)? UN: NO, We don’t have MOQ, Different customer have different requirement ,We can provide various capacity and size is per your requirements,Also ODM / OEM is welcome. Q: What is your term of payment? UN: PayPal, T/T, L/C, |
