1. First connect the B- line to the battery negative terminal (the B- line needs to be short-welded), 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 the BCO, connect the wire corresponding to the BCO to the total negative electrode of the battery (set the battery number as ①), connect the cable BC1 next to the BCO to the number ① battery positive, and the third cable BC2 to the number ② battery positive , The fourth cable BC3 is connected to the number ③ battery positive... and so on.
3. After connecting the cables, measure the voltage between each two adjacent cables from the header. The voltage of the polymer battery should be less than 4V, and the voltage of the iron-lithium battery should be less than 3.5V. Insert the cable after checking.
4. Connect the negative pole of the charger and the negative pole of the load to C-. B negative wires and C negative wires 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, and the protection board works normally if it is e
