Modules have a maximum stack size of 50, but inserters try to add 2x the recipe cost. Which conflicts with this mod since all the armors have recipe price of 30+ modules.

I actually like the price of the armors and their utility, but it is just annoying.

Uhh... that's a problem.
I could try to fix it by adding some new items that require all those modules and can help to fix this problem, but until then I think you'll need to install some mods to tweak the modules max stack size, 'cause I balanced the armours without considering this thing.
(I could make the mod modify the stack sizes in the first place, but this could lead to some problems with mods that modify stack sizes and honestly I don't think all this is worth it.)

I don't think that this is a problem. The reason that I don't think that this is an issue is that if you look at a assembly machine with a recipe for a nuclear reactor (mine in this example is output bound to 4 reactors in a output chest), the inserter's will fill the assembly machine with between 522 and 565 of either copper plates, steel, or advanced circuits (the concrete it fills closer to 800 for whatever reason). These are in stack sizes of 100 to 200. But they behave differently when in an assembler because of the storage in the assembler.

Yes, an inserter will TYPICALLY fill 2x the stack size into the assembler but it is dependent on the recipe.
