Why would you lose 12v when you pull the shore power cord? You should still be on battery. The battery voltage is not high enough to trip the BMS cut-off.
It seems a question of the chicken or the egg...If we assume that the BMS circuitry shutdown the charging process by disconnecting the battery from the camper (at voltage X), and the battery charges and discharges through the same cables, then how is it that there was no associated interruption in power to the camper?
I don’t claim to know the answer to this curiosity - lol.
