Wiring:
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.....B16; then insert the cable into the BMS;
(The maximum number of strings is 4-20 strings, the example picture is 16 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) .

FAQ
Q: How many Ampere protection circuit boards should choose?
A: 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?
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.
