So if I had something along the lines of the following:
How easy would it be to wire it into a micro-usb? Ultimately I plan to hook up my Pi power supply to a solar panel to drip feed my battery as it would only be on for a couple of hours a day at most, but right now I am just looking at logistics etc.
Yes I know other options might be better, and that the running costs of the Pi are low, but this is for the fun of it. A nice little fun project
I will look into the regulator - should be easy enough to wire in-front of the battery, although this is my first bit of electronics since school (10 years ago maybe?)....
