Welding point description:
B+ is connected to the positive pole of the battery;
• B- connect to the negative pole of the battery;
• B1 3.7V
• B2 7.4V
• MB/B1 is connected to the connection point before battery 1 and
battery 2;
P+ is connected to the positive electrode of the charging/discharging terminal (the charging terminal and the discharging terminal are shared);
• P- is connected to the negative pole of the charging/discharging terminal (the charging terminal and the discharging terminal are shared).
Notice:
(1) Please pay attention to the operating conditions of input and
output voltage and load current, so that the power consumption in
the protection board does not exceed the allowable power
consumption of the specification.
(2) When the battery is connected, it may not be able to discharge.
In this case, connect the charger to return to normal operation.
(3) When the overcharged battery and the overdischarged battery are
mixed together, it becomes an overcharged state and an
overdischarged state, and both charging and discharging are
impossible.
(4) Although the protection board has a built-in anti-static
protection circuit, please do not apply excessive static
electricity to the protection board that exceeds the performance of
the protection circuit.

Wiring precautions:
1. Installing the protective board requires a certain amount of
technical electronic knowledge.
2. When wiring, first connect the B- wire at the soldering pad
position to the total negative terminal of the battery (the B- wire
should be soldered to a short and thick wire) and solder the wired
terminal to the battery pack first, and then insert the protective
plate.
3. The connection between the battery terminal B- and the
protection board terminal B- should be short and thick, otherwise
it will cause the protection board to charge and discharge in
advance and malfunction.
4. You need to use thick wires when wiring P+/P-. Wires that are too thin and too long will burn the board!
