Comment on Two battery setup in camper
figurys@lemmy.world 9 months agoThat is correct. 1 battery for the engine and 2 for utility. I guess it has to be quite a beefy one. The interter is rated for max 166 amps. So that’s quite a bit. Which also makes it a bit hard to find a suitable relay.

12V 200A relays are pretty easy to find (I wouldn’t get one from alibaba tho), but that much current requires quite beefy wiring as well. Personally I’d review options to place auxiliary batteries in parallel since that would simplify wiring and the whole system a bit, but as I don’t know how your camper is built it can be tricky or you need to sacrifice storage space somewhere.
And as you’re placing a battery at the same space where people stay be careful with hydrogen. Charging lead acid battery produces hydrogen and in the worst case scenario, specially if you have a gas stove be dangerous if not lethal.
