5.2 Wiring Diagram (General Guidance)
Proper wiring is critical for the safe and effective operation of the BMS. Always refer to the specific wiring diagram provided with your BMS model for precise connections. Generally, the balance wires connect to each cell in your battery pack, ensuring correct voltage sensing. The main power cables connect to the battery pack's positive and negative terminals, and then to your load/charger.
Important: Connect balance wires in the correct sequence, typically starting from the negative terminal of the first cell (B-) and progressing to the positive terminal of the last cell (B+). Incorrect wiring can lead to damage.
