There are more expensive batteries that are sealed, thus do not need vented for gassing.  But the cost is very expensive, about 3x golf cart batteries.  We can do a battery closet, well vented and done if you have a spare closet that could be used.

Man, it's really not good.  Maybe if we were in the south it would be a better option.  We would basically make a cabinet that was moisture sealed and well insulated.  We would need to add some temperature controls to fan and a heating element.  I can have small fan relays that work by thermostat, a heating element that does same.  Just enough to take the edge off the extremes.

Although this isn't ideal, it is a very worthwhile path to blaze.  If we can succeed at creating an outdoor system, it's going to benefit allot of folks.

Here's a post about the project:
