One thing to be aware of is that the electronics is built to handle a certain
load. Putting a much larger battery, and load, could result in overloading
the circuitry. Also the charging circuit has to be able to charge your
batteries of course.

Granted, I've never done it with a much larger batteries, and I don't know
what kind of margins these circuits are built with. But I would imagine that
if you connected a car battery to one of these 500W, put over 500W load on it
and then turned off the AC you could easily toast it.

I picked up a 2200W for about $50 and spent 4 x ~$45 on batteries from a place
on US19 which also sells all sorts of batteries. Small building, but clean
and well kept.
