I'm a little addled because of a flu. Allow me to resend the post
below with a more sensible wording:<br><br>
I'm not sure how you insulate a space and at the same time vent it.
Any insulation is pointless if you have a draft flowing through the
area.<br><br>
If you are to insulate, then you must have an active venting system that
can open and commence venting promptly and reliably at the first
possibility of hydrogen gas emission.<br><br>
Being from a temperate climate, this has not ben an issue for me, but for
those of you in more extreme climates, how do you handle this
conundrum? Electric blowers with louvers?<br><br>

Batteries last longer if kept cool. However, a battery below 60 degrees F
(15.5 C) has reduced capacity. Temperatures above 77 F (25 C) increase
capacity only slightly but they significantly reduce battery life.
Batteries operating regularly above 85 F (29.4 C) lose have their

OK so you recommend insulation to keep them cool? For me,
insulation is more likely to result in higher temperatures in
summer. In winter, an insulated space is obviously ideal for
performance depending on the kind of winter (which seems to be a variable
these days). In summer, insulation directly on the battery seems
unlikely to keep them cool. On charge they will definitely need a
temperature sensor and will be likely to get hotter than ambient if
insulated.<br><br>
