I have no desire to create a firestorm of additional questions.
Suggest the OP research the boating forums and EV forums. Those folks have several years of first hand knowledge. Yes EV vehicles are a different application however the typical sailing boat application is similar to the RV House battery. Both of the above have extensive documented information and hands on experience.
For me the "store" bought BMS is not worth a nickle. Check out the many EV / Boating forms. Several documented fires have been created by this wonderful device that is sold to protect even a fool from any possible harm.
I designed and created my own home brew BMS with a integrated charging system for less than $50.00. It includes proactive Audio/Visual warnings & alarms and is completely integrated into my RV electrical system. Yes if need be it will automatically drive a 400amp contactor.
Everyone has their own requirements and skills.
I say once again you should stay away from the "drop in replacement" marketing hype
