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. Connect Charger C-/Load P- with BMS C-/P- (Use larger size wires)
4. Connect Positive Pole: Charger C+/Load P+ with Battery Pack B+ (Use larger size wires) .

3. Preguntas más frecuentes
|
q: ¿Cuántas placas de circuito de protección de amperios debería elegir?? A: Depende de la potencia de su carga, como la potencia del motor eléctrico, comuníquese con el servicio de ventas o soporte técnico antes de comprar.. q: What is the distinction between same port wiring and different port wiring? A: 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? A: 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)? A: 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? A: PayPal, T/T, carta de crédito, |
