Even if you used the same BMS and cell configuration for =>two parallel battery packs (to increase overall current), wouldn't you potentially run into charge/discharge balance issues between battery packs after a certain number of cycles? Talking about the same balance issues the BMS's are supposed to help prevent from occurring between the individual cells in each battery pack. If this did happen, one should be able to resolve it by top balancing the battery packs themselves, right?
No. The two packs are in parallel, so they will always see the same voltages and will be inherently balanced (just like the 30 or so cells in parallel inside a battleborn stay in balance). Within the packs, the cells are in series and could get out of balance, but the balancer in each BMS will keep them in balance.
