2. Setup and Wiring Installation
Proper wiring is crucial for the safe and correct operation of the DALY Smart BMS. Always ensure the battery pack is fully discharged before beginning installation.
2.1. Balance Wire Connection
Connect the balance wires to your battery cells in the correct sequence. The black B0 cable connects to the total negative pole of the battery. Subsequent red cables (B1, B2, etc.) connect to the positive pole of each cell string in ascending order.
Image: Detailed diagram showing the connection of balance wires (B0 to B13) to individual battery cells. B0 connects to the total negative, and B1 to B13 connect to the positive terminals of each cell in sequence.
After connecting the balance wires, use a multimeter to measure the voltage between adjacent wires. If the voltage difference between the batteries in each string of wires is less than 1V, the wires are connected correctly.
