Features:

Built-in high-precision voltage detection circuit;
The terminals connected to the charger use high-voltage devices;
Built-in three-stage overcurrent detection circuit (overcurrent 1, overcurrent 2, load short circuit);
The charge and discharge of the battery can be controlled through the MOS tube;
Wide operating temperature range: -40°C ~ +85°C;
Low current consumption.

Wiring Method:

B+ is connected to the positive pole of the battery;
MB is connected to the contacts in battery 1 and battery 2;
B－ Connect to the negative pole of the battery;
P+ is connected to the positive pole 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).

Precautions:

Please pay attention to the use 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;
When the battery is connected, it may happen that the battery cannot be discharged. In this case, the connection and charging can return to the normal working state;
When the overcharged battery and the overdischarged battery are mixed together, it becomes the state of charge and the state of overdischarge, and it is impossible to charge and discharge;
Although the protection board has built-in anti-static protection circuit, please do not apply excessive static electricity to the protection board that exceeds the circuit performance of the protection board.

Scope Of Application:

2 strings of nickel cobalt manganese lithium, ternary lithium, lithium cobalt oxide, lithium manganate ion rechargeable battery packs;
2 strings lithium polymer rechargeable battery pack
