One rugged enclosure for two batteries -- no separate boxes, no improvised strapping. The Camco 55374 keeps your RV, boat, or automotive battery bank secured, protected, and compliant in a single polypropylene shell.
Running a dual 6V GC2 battery bank is one of the most popular RV power upgrades -- and that pair needs a proper home. The Camco 55374 is purpose-built as a single elongated enclosure that positions two batteries end-to-end in one box. No stacking, no side-by-side improvisation -- just a clean, contained installation that works as well in a boat compartment as it does in an RV battery bay.
The box also fits two 12V Group 24 or Group 24M batteries end-to-end, giving weekend warriors and truck camper owners a solid dual-12V enclosure option. Heavy-duty UV-stabilized polypropylene construction handles engine compartment heat, outdoor exposure, and the battery acid vapors that destroy lesser enclosures over time.
Fits two 6V GC2 golf cart batteries OR two 12V Group 24/24M batteries positioned end-to-end in one box.
Meets U.S. Coast Guard CFR 183.420 requirements when used with GC2 batteries -- required for many marine installations.
Comes with 2 hold-down straps and 4 strap clamps with screws -- everything needed to secure both batteries is in the box.
UV-stabilized, acid-resistant construction handles outdoor exposure, road vibration, and battery off-gassing without cracking or corroding.
Side-by-side dual boxes take up more horizontal width than most RV compartments allow. End-to-end placement fits a narrower footprint -- critical for pass-through storage bays, truck bed toolboxes, and boat battery compartments with limited lateral space. The 55374 is designed around this layout so both batteries share a single lid and strap system rather than requiring two separate boxes and twice the hardware.
Two 6V GC2 batteries wired in series give you a 12V, high-capacity flooded lead-acid bank -- the preferred setup for RVers who dry camp or boondock. The 55374 is one of the few off-the-shelf enclosures sized specifically for this pair, eliminating the need to fabricate a custom box or use ill-fitting alternatives.
The included straps run over the top of each battery and attach to molded anchor points on the box body. Four strap clamps with screws lock the straps in position, keeping batteries firmly seated even on rough roads or in rough water. This is not a friction-fit lid -- the strap system is the primary retention mechanism, which is why the box can meet Coast Guard retention requirements.
The 55374 is used across a wide range of 12V power applications:
Always verify your specific battery's physical dimensions against the box interior before purchase. GC2 batteries from different brands can vary up to 1/4 in in each dimension.
