500mA Solar Lithium Charging Controller Board - Micro-USB - CN3065
The Li-Ion battery charger module is designed to work with solar panels. The module is based on the CN3065 chip. The charger can supply current up to 500 mA via 2-pin connectors for charging Li-Ion batteries and to power a load. The build-in Micro-USB connector has been added to provide additional charging when solar panel does not provide with enough power. The module input voltage is in the range of 4.4 to 6 V.
The CN3065 is a complete DC/DC in-line charger for Li-ion and Li-polymer batteries. The device contains a built-in power MOSFET. The built-in 8-bit ADC can automatically regulate the charging current. CN3065 is specially designed to operate within USB power specification.
When charging the battery, priority is given to drawing energy from the solar panel. However, when the load draw current is greater than the charging current, it will also draw power from the battery. After all, if the input is not enough, the battery will slowly discharge. If the load is small, the battery will be charged.
