Friends:
I'm a little addled because of a flu. Allow me to resend the post below
with a more sensible wording:
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.
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.
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?

I recommend insulation. In general, operating temperature is very
important. Batteries last longer if kept cool. However, a battery below
60 degrees F (15.5 C) has reduced capacity. Temperatures above 77 F (25

life. Batteries operating regularly above 85 F (29.4 C) lose have their
operating life.

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.
