Hydrogen is really only a problem in enclosed spaces. If the batteries are just sitting in the cabin, you're actually safer than if you were to build an enclosure for them. If you do end up building an enclosure, a small vent to outside would be fine, as long as the vent can't get clogged by bugs. Lead Acid batteries do best at around 20C, and fully charged batteries freeze around -40, discharged batteries freeze near 0C.

Can we talk about MPPT charge controllers in this thread? You know, the thing that goes between your solar panels and the batteries. I’m maxing out a 40amp one right now but I want to add more solar panels. I’m kind of eyeballing a half-off 100amp version on amazon warehouse deals. Can you connect two charge controllers in parallel to the same battery bank? Like in my case for a total of 140amps? Or do they not play nice with each other? Each charge controller would have its own array of solar panels, but both would feed into the same battery bank. Is that do-able? Sorry if this isn’t the thread for MPPT discussion. But I can’t find a better one and it seems relevant.
