Many campervans use a second deep cycle leisure battery charged via a split charge relay system. You are better to use a similar capacity battery if this is what you intend to do. if you feel you just need a beefier battery, then uprate yours with a larger capacity single battery.
If your completely crazy & have some daft idea about wiring your batteries in series then don't unless all your electrics are 24v.
Just be sure your alternator can cope with your requirements.

Use the feed to the alternator warning light (thin wire) to activate the relay

leisure batter is the way.....
would it not be a good idea to find out what he wants to do with the batteries first ?
and whatever the question is the answer will never be "leisure batter is the way"
"tractor batter is the way" i would agree with

Sean, we ain't running a creche here, that's why we gave him the choices. He's all grown up & will probably now make up his own mind now that he's got advice.
so when people ask a question that really doesnt quite contain enough detail are "we" now going to fire off numerous replies in the hope that one of them is actually the correct one ?

well i have to agree that you would need to know what his intended application is to specify "deep cycle" or "tractor" battery. both have thier merits and both have their disadvantages.
so what you need 2 for my man?

o yer, and that split charge kit you recommended is not rated hi enough if he has a winch or high wattage inverter installed.
what if he's got hold of some 6v comms batteries and is wondering if he can use 2 of them in series
do you now see my point about finding out what he's wanting to do before you start giving answers ?

i run two batteries on my disco, it is poss to conect them without all the fuss if you have a high output altenator, live to live, earth to earth, will give you 12v, live to earth and earth to live will give you 24v, i do this as a backup as i run electric winch and extra power on start up...

Well if we're going to get seriously stupid, then what if he's got hold of a couple of AA torch batteries.

Hey Maddie, the sad thing is that with some of the things posted by some of our more mentally challenged members on this & other threads, that actually sounds like a fairly sensible reply.
it must hurt having yer head up yer arse all the time
