In terms of BMS it could be hard to find one capeable of what BAC8000 can do (500-600A?), but you also could use something that does just voltage monitoring and tells you if one group has reached LVC. Then you stop manually.
It's possible the multi-pin connector on the stock pack can send a signal to somewhere to shut things down or switch to EP mode.
