Product Description
The 18650 lithium battery charging module with Micro USB interface can charge and discharge at the same time, the output voltage is adjustable, the default output is 9V, it can be widely used in DIY mobile power supply, PCB power protection board, mobile phone charging.

Specifications:
1.Before use, before debugging, the default output is about 9V.
2.Input voltage 4.5-8V.
3.The output voltage can be continuously adjusted 4.3-27V(4.3V or more, 27V or less, any voltage can be output, you can adjust the voltage counterclockwise).
4.Charging voltage 4.2V Charging current is 1A.
5.Discharge current 2A output current to calculate(Output reference maximum current 5V 1.4A , 9V 0.8A, 12V 0.6A Static current is about 0.5 mA).
6.Overshoot protection, yes; over-discharge protection, yes (2V cut-off boost, but does not block the output, the output is still 2V).
7.Cut-off boost 2V, depending on the situation, whether to add a protection board.
8.Size:33mm*23mm*9mm

Example of use
1.For example, VIN+ terminal connected to 5V solar panel BAT+ terminal can output 4.2V to 3.7V to charge the 18650 battery.
2.The OUT+ terminal can output an adjustable voltage, which can be adjusted by yourself.
3.Can be used for multimeters, modified lithium battery charging.
