DIY solar panel battery charger control board
Connection to Solar Panel

Use this control board to build your own solar panel powered battery pack, so that you can power your USB (5V) powered devices by the sun at locations without mains power, e.g. for remote monitoring, time lapse photography, etc.

After you have installed your own battery, you need to activate the board with a DC adapter, otherwise, the USB output port will not have power.

The board will be provided inside a PVC plastic box which is sufficiently large to house 3x lithium cell (18mm diameter x 65mm long).

For maximum capacity, you are recommened to install 3x 3.7V lithium cell in parallel.
