Yes those steel plates look 1/8" thick. They will be too elastic at that length and will not be able to spread 11 PSI compression force evenly across entire cell side. Leaving it the way it is now is fine as long as you don't care about corner cells which will act as force spreaders to remaining 14 cells in a stack but will not be optimally compressed themselves. This assumes those 4 springs are at 50 Kgf each for 200 Kgf total. I doubt it. So it looks like entire compression apparatus is not applying enough compression to be effective.Do you really think they're going to bend?
The yellow steel plates are 5mm thick, the springs are holding 75kgf each.Yes those steel plates look 1/8" thick.

it's clearly been designed with significant thought, would you be willing to share the 3d print files?The yellow steel plates are 5mm thick, the springs are holding 75kgf each.
I checked for bends on the plates and they have not bent at all.
It seems to be rigid enough but i will continue to check from time to time.
Sure. If the admins allow for file sharing i can share it no problem. I dont know if there is any rule about it.it's clearly been designed with significant thought, would you be willing to share the 3d print files?

I also can cad any bracket, holder, spacer, connector or weird part that doesnt exist in 5 minutes if anybody needs it, i do it all the time.
There you go, i have attached the stl file of the templateit's clearly been designed with significant thought, would you be willing to share the 3d print files?
I think there should be a section in the forum for file sharing, manuals, sketches, stl and cad files, etc, you know?There is no rule against sharing STL files. Treated no different than any other file type. Now if it is a multi-gig affair that might be different
They should be in a holder. The fuse is not structural, and the wire will be free to short out power from the other batteries.I have put class T fuses directly on the dc breakers of each battery, they are small so is difficult to see them.

Yes i have been concerned by this. I will probably diy a holder connected directly to the main busbar, or even better just to 3d print a bracket that will clamp the positive and negative wires before the dcbreaker connection.They should be in a holder.

Oh i see. I am not sure in what category stl and cad files should belong though. Beginner's resources?
