This is indeed, a great project I i'm inspired to make something like this.
I would like to ditch the 80aH battery ( since it's bulky and I would like to keep the battery indoors without risking messing up my house.
So I would like to know if I can replace that 80aH battery for something smaller like:
I'm guessing 2 or 3 of these connected to a converter (not sure if this is the right term, but I want the batteries to provide power without any power downtime ) to provide the Pi a 3 battery setup.
That way the batteries would be constantly charged by the panels.
