"Battery input and output power decreased; capacity increased."

Battery capacity is 5.0 MJ, same as vanilla in 2.0. Did you revert a capacity increase or did something change?

Probably a bug. I'll check it out.

I moved this mod to https://mods.factorio.com/mod/physics.

I did check that out, btw. I found that it scaled correctly with my original calculation so the lack of capacity increase was intentional, but I may add it as an option if this is desired?

No, the balance worked fine IMO, just wanted to bring it to your attention in case it was an error.
