Putting your batteries in series will combine their voltages, don't do that.

Put them in parallel, assuming they're all 12 volt, and you'll have a twelve volt bank.

Oh boy. Explain the difference now before I blow myself up.

Hang on how about this? Each battery gets a line individually to the ignition battery and I draw the power from both auxiliary via a one positive and one negative line.

What are you trying to do?

What I drew.

I have two spare batteries now

I need to run my fan and light off the auxiliaries and charge them with the ignition battery with a switch so that I can isolate the auxiliaries and not drain the ignition.

You should just wire them in parallel.

If you wire them in series, you will double your voltage. Wire them in parallel and you keep the same voltage, but double the capacity, which is probably what you want.

Ok so I draw power from one individually. Got it

It's more like just making a bigger battery.

If you need more voltage, then you wire batteries in series. But if you do that in an automobile, I think you might sometimes burn out fuses (not totally sure about that) since you are increasing your voltage.

I think the more sophisticated custom vans that have multiple batteries actually have separate circuits. So a fridge or whatever is on a secondary circuit.

And deo is probably correct about the alternator. I think this is why they usually make separate circuits for the luxury appliances.

What is a series? Where you draw power from the positive on one and the negative on the other while both being grounded?
