Welding point description:

·B+connected to the positive pole of the battery;

·B - Connected to the negative electrode of the battery;

·Connect MB to the connection point before battery 1 and battery 2;

·P+is connected to the positive electrode of the charging/discharging end (shared by the charging/discharging end);

·P-connected to the negative electrode of the charging/discharging end (shared by the charging/discharging end).

Reminder: When assembling a battery pack, the battery voltage, capacity, and internal resistance should be paired properly. The battery voltage should be around 3.7V at the rated voltage, and there should be no output after assembling the battery pack. Charging with 8.4V voltage is sufficient.
