Never a problem.
However any enclosed space should have *some* ventilation to get rid of hydrogen gas.
"Enclosed" may be a misnomer. Looking at pics of the OP's trailer suggests his battery storage area which is hidden behind a removable panel on the trailer's front cap is probably much the same as the removable panel on my previous KZ Spree, behind which sat a pair of 30 lb propane tanks. Yes, that compartment was "enclosed" but it certainly wasn't sealed but rather was a molded space, part of the trailer's front cap - so whether used for storing tanks or batteries that area was not part of the trailer's front pass through cargo compartment but was in fact a separate compartment with plenty of ventilation. Unfortunately the OP hasn't provided any pics of this "enclosed" battery space but I'd suspect he doesn't need battery boxes at all.
You are correct enclosed is somewhat of a misnomer. It is a weather protected area, but is not part of the under bed through storage. I probably don't need a battery box, but they are a little easier to anchor than the batteries alone. I can bolt the boxes to the deck or throw straps over the covers.
