Relay on the leisure batteries?

[Sp0_0k]

Is there a relay on the leisure batteries preventing from discharging them completely?
I never went too low voltage to check that, and most my equipment like fridges has its own relays.
Anybody ever discharged them completely?
I am pretty sure nothing like that on main battery with lots of cases battery drained from radio system.

No. On the Ocean/SE although the fridge and Parking Heater will stop if the Leisure Battery Voltage drops to 11.5v this is due to their own internal monitoring/requirements. There is no such monitoring on the Habitation lights or 12v sockets so if they are On then the Leisure Batteries can be totally drained. Cannot see it being any different on a Beach.
