Feature:
1. . Battery overvoltage protection.
2. Constant current/constant voltage operation with thermal regulation maximizes charging rate without overheating risk.
3. Automatic low power sleep mode when the input power voltage is removed.
4. C/10 charge termination.
5. Automatic recharge.

Specification:Item Type: Lithium Battery Solar Charge Module
LED Indicator: ''CR'' LED is charge status indicator; ''OK'' LED is fully charged OR constant voltage mode
Dimension: 18x10.16x2.7mm
Options: with Pin, without Pin
Weight: 0.9g(with Pin), 0.6g(without Pin)

Instruction:
The adaptive unit on the module can adjust charging current automatically based on the output capability of input power supply, so it is ideal for the solar-powered systems, or the applications that need to charge lithium-ion battery or lithium polymer battery with an input power supply whose output capability is limited.
If your solar panel is 5V, then you can use it directly. Of course, the module can also be powered by a 5V DC power supply.
