Too much tongue weight for my two 6V golf cart batteries, so I boxed and vented them in the galley. Put a clear acrylic cover so I can see them and so border security won't wonder what's hidden.

Your'e right, your basic marine battery vents hydrogen. It looks like your only option is inside.

AGM batteries are sealed -they don't need to be vented.. They are a bit more expensive but do not vent, and I think you can install them on their side if need be. You might search AGM batteries on this site.

The other option is a marine battery, inside, but vented to the outside. It's not infrequently done that way. They make battery boxes just for that issue I think.

Yup, if you put it inside, build a box sealed to the inside and vented to the outside.

I have a tear with galley. My battery is in the galley at the floorboard. Sealed to the sleeping compartment, vented out through the galley.

Mine too
