Firstly connect the batteries in series 2. Ensure that the voltage of each string is the same (the difference between the highest voltage and the lowest voltage is preferably within 0.1V), and the voltage range is between 3.2-4.0V. 3. Firstly connect the distributed cable, connect according to the diagram, and insert the cable port into the board port after checking it is correct (first connect the battery, then insert the board, the step cannot be reversed). 4. Check whether the total positive voltage of the C-port and P-port to the battery is equal to the total voltage of the battery. If they are equal, the board is working normally. 5. Solder the battery negative B- to the port marked B- on the board. 6. Both the battery output negative electrode and the charging negative electrode of the same port board are connected to the port marked C- on the board (the P- port is just floating).
