Clarification request for new battery system+Recharging station. (possible bug)

So the new battery system is interesting, i’ll give it that, but i’m currently having a few issues with it.
Namely: The normal (rechargable) batteries will recharge in a charging station, but for some reason will not if loaded into a tool. I’m curious if this is an oversight, or just a really tedious feature. Side note: The UPS bionic appears to simply not function in regards to charging batteries/tools, is the code simply not up to date much like the old UPS compatible battery mods?
I know i could put this on the github, but i’m not clear if this is an issue or not.
