Are lithium batteries worth the cost?
I can carry two group 29s in my AF1150. Are they worth it?

BMS does not throttle power. On or Off with a MOSFET or Relay. BMS is really the last resort to save the battery. You should have a voltage alarm to reduce power or keep track of the state of charge and temperature with the BMS APP. There is no load shed like there is for 120 volt systems that I know of.
Similar can happen to lead-acid but there is no limit to discharge and possibly freezing up and killing the battery. So it is the same type of monitoring if you are in extreme conditions. Possibly need a generator auto start in either case.
