Interesting discussion of battery box.
http://www.solar-photovoltaic.info/solar-electric/battery-box/
I plan to use AGM batteries, which negates most concerns. They are "sealed" and only emit tiny amounts of hydrogen except under extreme current overcharging (which can be avoided by proper charge controller.) With AGM batteries, I can have batteries inside pool house, in relatively moderated temperature, with minimal venting, and modest separation from electronics (on other side of room.
Since I've decided to go back to hardipanel siding instead of brick, the question of having interior sheetrock has come up again, and then the issue of interior venting. I still think it's useful (or even moreso) to have interior insulated sheetrock walls and ceiling. The only significant reason not to do so is cost. So it depends on how things pan out. If I get building built at reasonable cost, I'll go for an additional phase adding sheetrock as previously thought out (including special sound-absorbing sheetrock on ceiling and front wall) and then have small vents (already purchased) at uppermost ceiling height. Such vents could, in principle, be sealed if they prove undesireable or unnecessary.
Otherwise, if the roof itself is the ceiling, the ridge vents provide all the needed venting (and more) for AGM batteries inside (and possibly even vented batteries, though vented batteries also emit acid...not good for my stored stuff).
