> If you want a single burner had you thought of induction? I know they are getting a lot more popular in the states for campervan builds, you can then potentially forego the lpg cylinder, fit an extra battery and still save a little space. I looked at a few but they don't make much sense for my build.
What sort of battery would you run an induction hob off?
If your hob was 1.5kw, you'd be looking at 125A not counting for losses in wiring and the inverter, so probably a good 150A current at the battery?
I know you're probably only going to use full power for a few minutes at a time to boil water or fry meat, but still I would want to put that kind of load onto a lead acid battery repeatedly unless I had a pretty large bank of them... Boiling a pan of water would be like running your starter motor for five minutes.
Even with LiFePO4, you're probably going to need a couple of 100 Ah batteries to handle that load, and if used daily you're not going to be able to recharge from solar, so you'd have to be running the engine daily?
