Charging a lipo battery with a solar panel.

Diy solar li ion lipo battery charger step 1. A lipo charger. This is a super mini solar lipo charger based on the cn3065 a single lithium battery charge management chip. Remove the prog resistor.

It s a plug n play charger for any 3 7v battery and only requires a 6v solar panel. This solar charger provide you with the ability to get the most possible power out of your solar panel or other photovoltaic device and into a rechargable lipo battery. If you disregard the not float charged requirement one option is simply to connect the lipo battery to the solar panel via some diodes or a zener diode which would limit the maximum voltage to around 4v most batteries seem to require charging to 4 2v. In the interest of having self sustainable outdoor electronics projects i began to experiment with charging lithium polymer batteries with solar panels initial test this past week march 23 28 i ran an experiment to see how well the solar panel i purchased would charge a single celled lithium polymer battery.

There are a plenty of choices for charging and regulating those batteries too but only a select few when it comes to solar charging them.
