It would be nice if you could set up a setting so that recharging a battery takes some kind of resource, let's say copper or iron, so as to introduce a consumption to it instead of just recharguing it, like pyanodons did for their nexelit batteries.

This mod’s batteries are supposed to be simple batteries. All the batteries I own don’t consume any physical resource, only electrical energy, and I would like to keep this mod’s batteries just as simple.

If pyanodons already provides what you want, why don’t use use that instead?

that's why I ask as an optional feature, but good enough argument, thanks!
