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.

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.
