RE: your battery box for 300 lbs of batteries.

Here is an example where plain polyester resin and fiberglass mat and roving applies.
Cheap and strong.

I had a question about their thickness vs. the batteries weight myself. As 3mm (1/8") isn't what you'd call stout, even for just one 50lb battery.
Triple the thickness, or at least double it.
