This protection board is protected by AO MOS tube and Ricoh lithium polymer rechargeable battery.IC;

&Features:

(1) Built-in high-precision voltage detection circuit;

(2) The terminal connected to the charger is a high withstand voltage device;

(3)Built-in three-stage overcurrent detection circuit (overcurrent 1, overcurrent 2, load short circuit);

(4)byMOSThe tube can control the charge and discharge of the battery;

(5)Wide operating temperature range:−40°C ~ +50°C;

(6)Low current consumption.

&Technical Parameters:

&Welding point description:

· B+Connect the battery positive pole;

· B-  Connect the battery negative pole;

· MB  Connect the connection point between the battery 1 and the battery 2;

& Product Wiring Diagram:

&Precautions:

(1) Please pay attention to the 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, there is a possibility that it will not discharge. In this case, the connection charger can be restored 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 charging and discharging are impossible.
(4)Although the protection board has an anti-static protection circuit built in, do not apply excessive static electricity to the protection board that exceeds the performance of the protection circuit.
