Yes....hence my comment

However those ones are quite heavy duty....I guess you could get away with a 10amp one...not sure what power rating your fridge is but I doubt the combined power consumption of the fridge and a fully charged battery is going to be more than 10A.

10A ones are cheaper  ;)

If you've got to get up anyway, you might as well walk a decent distance away rather than do it in your wardrobe, as far as I'm concerned. :o

Is there not a 12V to 12V DC to DC converter available for battery charging purposes (may be as per used on solar panels)?

The caravan fridge when on 12v is controlled by a relay that only activates when the alternator is charging the main car battery, not worried about that as it can look after itself.

The caravan battery is on a direct feed from the car battery, and as such can give a reverse drain back to the car battery if the alternator ecu is not charging.

This feed also provides power to the Al-Ko ATC system, but is isolated from the caravan battery.

I need to isolate that feed to stop this happening, the caravan does not draw any power from its own battery whilst towing and will remain fully charged if not connected to the car allowing me to use the mover.

Why not use a conventional voltage sensing relay? That will connect the caravan battery when the vehicle electrical system is at a high voltage and disconnect it when the voltage drops. You'll get some charging of the caravan battery when the vehicle battery is being charged and it will protect the caravan battery from being discharged.

That seems to be the best option, if I could find one.

Would this do the trick?
