Would it work to make a battery pack that can be used both 13S and 14S
A dedicated 48V charge/discharge cable connected 13S, with a 13S BMS, and at the same time, wired in parallel, a dedicated 52V charge/discharge cable connected 14S, with a 14S BMS.
After being used 48V / 13S it would be charged 13S, the 14th group neither charged or discharged, because it is not connected to the 48V charge/discharge cable.
After being used 52V / 14S it would be charged 14S, all groups charged and discharged.
It would be important to charge it the way it had just been used (13S or 14S) so all parallel groups being charged are at similar charge.
Since the BMS are connected simultaneously would they interfere with each other?
