Type-C 5V Charge Discharge Integrated Module 3.7V 4.2V 18650 Lithium Battery Charging Boost Power Board Protection

Product Features：

1. Small volume. Smaller than similar products.

2. 4.5-5.5V power supply, applicable to a single lithium battery (unlimited in parallel), with a maximum of 1.2A. It can be used to stabilize 1A current as required.

3. Applicable to all types of 3.7V lithium batteries, including 18650 and aggregate batteries.

4. With overshoot and over discharge protection, the over discharge protection is 2.9V, and the charging cut-off voltage is 4.2V!

5. When there is no external input voltage, it will automatically switch to the output mode, supporting small current, output 5V, and output about 450mA. If 1a is output, the voltage will be about 4.9V-4.5V according to the power situation.

6. Automatically switch the input and output, and charge the battery when the external voltage is input. Otherwise, when discharging, the charging green light flashes, the full green light stays on, the light does not light when discharging without load, and the blue light is on when discharging with load. Standby power consumption is about 0.8mA.
