What are people using as a battery backup?

I use a solar charge controller(about 1 lbs) and pretty much any battery. Currently I use a 36v lipo pack out of a hover board and a 32v LiFepO4 pack out of a scooter. I get 1.5 charges out of the lipo and 2-3 out of the LifepO4(higher capacity)
There is a "convince Andy to build this sh*t" thread that has info from the guy who came up with it. I'm just an adopter.
