Ex got M3 in the divorce, waiting for EU Model Y!
I know that
However, if these couple of modules somehow separated from main pack and maybe used as that extra (10kw) brick protection, X can just use entire 85kw for driving
This also may not require cooling if it's not being used
Sorry, no just no, that's not how it works. Either it's part of the battery or not. I.e. if any additional cells/modules are connected the whole thing will act as one larger pack, regardless of if those cells are physically in the actual pack or not. I would be super amazed if we saw this kind of sloppy engineering from Tesla. In fact I'd bet heavily on this not happening.
