Battery Box options

I'm switching from a single 12V battery to 2-6V GC batteries. Looking at battery boxes, I find that a single 6V box can be bought for $10-20 while a dual goes for $75+. Any problem using 2 singles? My batteries are protected in an enclosed area at the front. Other options?

  • Other than when checking fluids, going with separate battery boxes for our pair of 6 volt GC2 batteries has served us well, they sit on a exposed rack on our a-frame. Didn't want to pay the inordinate upcharge for a dual battery box as two singles could be had for a third of the price and were readily available locally. Great move to go with a pair of golfcart batteries, we love ours and find a pair of 6's suits our needs just right, even when RVing off the power grid.

    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.

    Leakage? Maybe, but my biggest issue is spillage when taking samples for Sp.Gr. readings.

    If your batteries are already in an enclosed area what's the advantage of putting them in battery boxes as well? :h

    In all the years we've owned a variety of trailers I've never once had any leaking battery acid. Regardless, if this is an issue for the OP then the better solution would seem to be a pair of AGMs.

  • I have two boxes with no issues but one box would be easier for water checks.
