Usage
Connect the battery charger to a standard micro USB connector and the battery connector to a battery. The LED is lit up while the battery is charging and turns off when fully charged.
Caution
Using a battery under direct sunlight may cause overheating, which could result in invalidation or fire. Battery should be charged with proper charger, in compliance with correct operation instructions. Never charge a battery unattended!
Development
It is possible to chain multiple chargers together to create a multi battery charger. The P2 connectors on the chargers are simply soldered in parallell.
Below are pictures of one possible setup. Don’t forget to check the rating of the connectors and make sure you use a power supply that can supply at least 500mA per charger.
