Third Battery Instalation in Camper

Hi Algee, for a start you will need to run heavier cable than your standard trailer plug can handle and there is a lot more to it than that.
Go to my web site and e-mail me from there.
You don’t have to buy anything, I’m only to happy to give you an idea of what you will need and you can take it from there.

Dear Algee,
I have a simular setup for my Jayco c'van and I have used 4aswg to charge the battery in the caravan. You will also need a 175amp Anderson plug to take the cable. Although the cable is not truly auto cable it is very flexable and oxygen free. I am also using an eighty amp soliniod switch in the car.
I can give you more details of the cable if you wish. On start up I am charging a DCB which is mounted on the drawbar of the c'van at 30amps. This drops down as the battery charges

Algee,

I have a battery on my camper which is charged from the car via a heavy cable and a 11 pin flat plug. (Carries the standard 7 pins for the trailer plus 4 extra heavier pins for other accessories). It has been working fine for about 4 years now.

What the others are offering above will probably work even better. That would be good. But whatever you put in don't rely on it to bring the c'van battery back up when it has sat doing nothing for 6 months. Before you go on a trip plug the battery charger in for a week or so of trickle before you set off. That way the cars alternator only has to top it up.
