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......B4; then insert the cable into the BMS; (The maximum number of strings is 1-4 strings, the example picture is 4 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) .

| Q: How do I judge what material my battery is ? A: Please take a look at the battery body. LiFePO4 battery: 3.2V or 3.3V. Li-ion or Li-polymer battery: 3.6V or 3.7V. LTO battery: 2.3V or 2.4V. Q: How to choose a suitable BMS/PCM for my battery packs? A: Please tell us following required details and we will advice for you: Battery material & Battery series & Capacity & working current & Application (For example: LiFePO4 BMS, 13 series, charge 40A, discharge 40A, application for e-bike 1800W.) Q: Do you have Minimum Order Requirement (MOQ)? A: Small PCM: 10 PCS MOQ; Large PCM: 1 PCS MOQ. Sample orders or bulk orders are all welcome. Q: Can I require products size? A: We can provide various size and specification is per your requirements, also ODM / OEM is welcome. |
