Compression springs do not offer an even 11 psi if they are not distributed evenly, as that is often the case (especially if there are none between battery packs which is often the case).
Springs should thus be adjusted to each offer a separate force.
I've posted about it on and I don't have a very conclusive solution. The two takes are using a FEM tool to calculate the force/stress across, and/or putting an additional plate with springs sandwiched between two plates.
Neither of these solutions seem very straightforward; I couldn't get FEM to run in FreeCAD without error, and the additional plate seems a bit tricky since the springs could only be held in place from at most one of the plates, but I guess that's likely not much of an issue.
I think my example is a bit extreme as I have most of the springs on the bottom ("floor" support) and I avoid them on the top (conductors). Am I overthinking it and I should just use a few bigger springs on the sides and call it a day? Or the additional plate is a pretty good way to go about it? Or there's a best solution out there?
