In my patrol i have a low voltage cut out device that switches off at 12.2v this i believe is a safe level at about 50% capacity of the battery,and still starts the patrol easily.However i note that on evakools site their fridges have a low voltage cutout set at 9.6v from the factory wouldnt this discharge damage the battery and also prevent you starting the patrol if the battery is down to 9.6v.
In my patrol i have dual cranking batteries in parallel.

Above 9.6v is the safe operating range of the fridge, they are protecting their product not the battery,
Have a good one

Hi Pepper
12 TO 12.2v is a good setting to protect your battery ,especially if its likly to be frequently discharged to that level .I believe most frig low volt cutouts are more to protect the fridge than the battery.

Pepper, can you separate the batteries with a 'smart switch'? You only need one battery to start the Patrol so can set up the other for the accessories. The smart switch (or whatever it is called) will allow the second battery to charge but not be used to start the car. Keep it for fridge and accessories. If need be, you can use it to start the Patrol with jumper leads.

motherhen,over the years have had 2 exensive electronic smart switches fail now have a manual switch that allows me to isolate a battery or run on one seperately or both in parallel,by fitting a low voltage cutout set at 12.2v it doesnt matter wether you have one or both batteries connected as if both are discharged to 12.2v you can still start the patrol use the hf etc.
I was making the point that fridge manufacturers set too low a voltage to extend the time the fridge runs but at the expense of damaging the battery

Hi Pepper
As the others had already answered your question; being that the fridges are set to look after themselves not your power source, i added what works
well for us.
