MPPT Li-ion battery charger

This MPPT Li-ion battery charger chargers your Li-ion battery with 1A, using a solar panel that outputs 4.4-6V. It is ideal when you want to use a Li-ion battery as a power source when you go camping or hiking and there is no power to charge your battery with, to power your light.

If needed, the MPPT Li-ion battery charger power source can also be changed to a normal 5V power source and it will still charge the Li-ion battery under the correct conditions.
