Add to the list...I've had good luck with Grace roofing underlayment:
tough and to a degree, self-healing, sticks to itself (and anything it
comes in contact with) very well making seams secure, easy to find at
building supply store, sticks aggressively to battery box sides without
mechanical fasteners, experience has shown it resists acid. As with
other solutions, something to uniformly distribute the weight and
irregular bottoms of batteries should be employed.

Ray,
Just a couple of weeks ago we installed a 24V HUP set in an existing
installation. We had an existing plywood battery box made of Baltic
Birch (the 9-ply 12mm thick plywood typically used for cabinet drawer
carcases) with a liner made of 40(?)-mil pond liner material. We
removed the six cells from the steel case, set the case in place in
the plywood box and lowered the cells into it. However, the box had a
non-removable 5" wide strip across the top rear, and we needed to
slide the entire 1100 pound case back about 8" in order to fit both
steel cases.
Before setting the steel case in the box I sprayed the floor of the
pond liner with a layer of the new spray pulling lube from Klein
Tools, then set the steel case in place and lowered the cells. Using a
Porta-Power and some blocking, we slid the case into place with little
effort.
You might find that vinyl pond liner works well in a plywood box. We
found it at a Home Depot.

Hi All;
We're looking to improve our battery box construction, and are
considering using 1/8" think polypropylene sheeting. I've used small
premade boxes before, but this will be for a HUP install, and we
would want to build the box around the batteries after. Does anyone
have experience/ comments on welding plastic? The alternative would
be to just seal the seams with acid resistant caulking. (silicone,
Geocell, ?)
I've had good luck in the past just using 10 mil plastic sheeting
stapled up on the inside of a plywood box, but we will be scooting
1000 lb batteries around on it, so I don't think the sheeting will
hold up.
Thanks,
