Welding Point Description:
· B+ is connected to the battery positive pole;
· B- is connected to the negative pole of the battery;
· MB is connected to the connection point between battery 1 and battery 2;
· P+ is connected to the positive terminal of the charge/discharge terminal (the charge terminal/discharge terminal is shared);
· P- Connect the charge/discharge terminal negative (common to the charge/discharge terminal).
Warm reminder: When the battery pack is combined, the battery voltage, capacity and internal resistance should be matched well. After the battery pack is assembled, there is no output. Use 8.4V voltage to charge.
