I’m thinking it’s a BMS limitation, where it can only balance x number of cells safely/reliably. Either that, or the way the modules stack might get too physically unstable.
Or it could just be arbitrary limitations; greed.

SatansMaggotyCumFart@lemmy.world 3 weeks agoBut my question is why only four stacks in parallel?
Why can’t you do eight in parallel because you’re only increasing storage but keeping the voltage the same.
If you read the rest of the thread you’ll see why I’m asking the questions here.

This I don’t know, but probably some limitation with the control software or some similar issue.
