Yes. They have 72” threaded rods. But my cells will be broken into 4 groups (4 wide x 4 high) and 4 shelves of 16 per shelf :Yeah, my concern with plywood is that it's flammable. Not that it should be getting hot enough to start a fire, but I've had some close calls before with some faulty fuses (always use a UL rated fuse). My concern with using metal is having some kind of accidental contact with the metal and the terminals. Right now I've ratcheted them directly, but I'm looking at cutting out pieces of tile just slightly larger than the cells, and strapping ratchet straps around those so the inflammable tile compresses the cells. If only I had a tile saw...
Do they make threaded rods long enough for 16 cells in a row?
I am using the 5/16” aluminum because I didn’t want anything flammable inside the cabinet just in case there was an issue. I am very concerned about accidental arcing from a bus bar/wire if you’re putting together or working on a pack.
I am using thin plastic matting between each cell and cell/aluminum plates.
I have coated my rack with liquid rubber to prevent accidental arcing and will do the same with my aluminum plating. However only the 5/16” edge will be the exposed part so it’s possible, however unlikely with that little surface area showing creating an arc...
One thing my diagram does not show, I am actually putting two threaded rods between every pack of four so I have consistent and even pressure on each and every pack.
