Going on from my first experiment, this one will be slightly different.

I will be using a 12v to 5v USB converter and a 12v AA battery caddy. This caddy stores 8 x AA 1.5v rechargeable batteries. This design will closely simulate my end design which will include a charge controller and a 60w Solar panel.

I did not commit to this design by soldering the wiring and connecting permanently as its a quick dry run test. I simply want to test the duration in which it will power a raspberry pi with a wifi dongle.

Unfortunetly the results sucked! Taking into account that the batteries are not new, the raspberry pi ran for 4 hours and 37 minutes.

This is a poor a result and is sending me back to the drawing board in regards to my design. I need to think about getting a sealed lead acid battery with some decent capacity.
