Foam compresses 25% at 11psi.
If you buy 1/4" foam, then plan for 3/16" between your cells when you design your busbars and your box, and you have 11psi compression with no springs and no hassle.
Worked great for me.
I designed my box to be slightly longer than the uncompressed length, and added a compression plate to push the cells and foam together to achieve the compression I wanted.
editing to add my later post here:
IMO, if you're going to compress the cells, you want to have foam in between them. All these fancy spring rigs would be much safer with foam compression pads.
