I jab aquick questions regarding the best, most efficient way to set up our batteries. We have a normal car battery in the car and a deep cycle in the van. I asked the guy doing our brakes and plugs etc to connect another deep cycle in the aux battery space in the car. He reckons it's best to have to have the car battery charge the aux battery, and the aux trickle charge the van battery. My question is, do you think this is the best way? Some people say that they should be completely isolated so we use one or the other, rather than both. I've even heard ppl say to connect the two batteries and use both at the same time. I'm really confused and would love to hear your suggestions?

Troopys info is good,, I have a redarc on the Tojo.
For van 2 batteries read this,, don't worry too much about 4 batteries in a bank but toward the end it deals with 2 batteries.
I would put the 2 deep cycle in the van together and charge together, and use together, however as one is old and one will be new you may have different internal battery resistance and therefore they may not last long (th old one that is).
Maybe buy 2X12 volt deep cycle together or 2X6 volt (big ones).

Hi Julie, I have just stared to investigate adding another house batteryand the best most simple "how to" info i have found is at
www. smartgauge.co.uk/batt conn.html i think thats correct if not try googling smartgauge.
Very easy to follow

This is how I set mine up for the camper trailer.
Firstly a Redarc Smart Battery Isolator to add an Auxilliary battery to the Troopy, using the start assist configuration (gives you the ability to jump start from the AUX battery.
Then a BCDC1225 DC to DC charger with solar input in the camper trailer like this.
Originally I set up the DC-DC charger to feed from the alternator via the isolated supply. That is basically from the Troopies AUX battery positive terminal. But due to some other electrical problems I was having during a trip, I reconnected the BCDC1225 straight off the pos of the Troopies main battery. Either way will work OK, but possibly better to fed the BCDC1225 from the AUX pos terminal. Something to note is in either case it's not the vehicle batteries that are feeding the house battery, but the alternator, due to the fact that you won't have any current back to the camper trailer (in your case van) unless the ignition is (connected via ignition controlled relay) or or the starting battery positive terminal voltage rises above above 13.2V (again when the ignition is on and starting batery charged).
