How to connect the BMS to the battery pack ???

1 Start from the B- line to the battery negative terminal (the B- line needs to be welded with a short wire first), and then connect the flat cable (before connecting the flat cable, you need to unplug the flat cable from the board).

2 Start wiring from B0, connect B0 to the total negative electrode of the battery (name this string not numbered 1), connect the cable B1 next to B0 to the positive electrode of No.1 series, and connect the third cable B2 to the positive electrode of No. 2 series. The fourth cable B3 is connected to the positive terminal of battery number 3 ------ and so on.

3 After connecting the cable, measure the voltage between each two adjacent cables from the header. The voltage of the Li-ion battery should be less than 4.2V, and the voltage of the LiFepo4 battery should be less than 3.5V.

4 Connect the negative pole of the charger and the negative pole of the load to C-. B negative wire and C negative wire need to be welded with thick wires. The wiring method has nothing to do with the color, only the correct order is required.

5 Then measure whether the total battery voltage is equal to the output voltage of the protection board,if it is equal then means the BMS works normally
