Camco Double Battery Box (55375)
Interior dimensions: 21 ½ inches long × 7 3/8 inches wide × 11 3/16 inches high. Capacity supports two 6V Group GC2 batteries or two 12V Group 24/24M batteries. Construction uses heavy-duty, corrosion-resilient polymer to protect batteries and resist outdoor elements.
Best for: Trailer owners who need a compact but capable dual-battery housing in a v-nose space. The polymer body resists corrosion and helps prevent battery leakage from spreading to other trailer components. The two-battery design is ideal for small RVs or utility trailers that require backup or dual-power configurations.
Limitation: Large dual-battery setups beyond the stated Group sizes may not fit this interior footprint. Plan battery dimensions before purchasing.
Camco Large Battery Box with Straps and Hardware (55373)
Interior dimensions: 7-1/4 inches × 13-1/4 inches × 8-5/8 inches. Features a lift-off lid, durable woven hold-down strap, foot clamps, and stainless steel screws. Made from lightweight, corrosion-resistant polypropylene and fits Group size 27, 30, and 31 batteries.
Best for: Trailer batteries that require a robust mounting system with hardware and a secure strap to minimize movement while driving. The included clamps and lid help protect the battery from jostling and exposure to road debris.
Caution: Some larger Group 31 configurations may press the lid if installed in tight spaces. Verify available depth in your v-nose enclosure before buying.
Attwood 9067-1 Vented Battery Box
Interior measures 13.06 x 6.9 x 10.5 inches, designed to securely hold Group 27 batteries up to 10.5 inches high. Acid-resistant polypropylene is tested for extreme temperatures (-20°F to +120°F). Integrated ventilation allows gases to escape, while a protective cover minimizes water intrusion.
Best for: Marine and RV users needing ventilation to manage battery gases and long-term durability in wet or salty environments.
Limitation: Venting design is optimized for larger Group 27 batteries; ensure your size fits within the interior clearance for your specific model.
NOCO Snap-Top BG27 Battery Box
Designed for Group 27 batteries and compatible with Group 24 batteries in many setups. Features a reimagined snap-top design for structural rigidity and easier installation. Pre-drilled internal pilot holes support direct mounting, or use the strap mount system for rugged installations.
Best for: Users who want straightforward installation with minimal wiring, plus a sturdy enclosure suitable for marine, automotive, and RV applications.
Limitation: Some configurations may require additional mounting hardware depending on boat or trailer layout. Confirm the mounting surface compatibility before purchase.
Peastorm 12V Battery Box (Group 27 Black)
Steel dual-battery relocation kit designed for Group 27 batteries. Features a black spray coating for weather resistance, side handles, lockable upper cover options, and bottom fixing holes with screws included. Reserved holes are protected by rubber rings to minimize dust and moisture ingress.
Best for: Trailer setups where steel construction and secure, lockable access are priorities, especially when relocating and organizing two batteries close to a v-nose tip.
Caution: Steel boxes are heavier than polymer options; ensure your trailer hitch and chassis can support the added weight during transport and handling.
Buying Guide
What size battery boxes fit a v-nose trailer? Look for interior dimensions that accommodate your battery group size (e.g., Group 27, 24, or 31) with extra clearance for venting and wiring. If you use two batteries, confirm the interior length and width can support both units side by side without crowding terminal access.
Material matters. Polymer boxes resist corrosion and are lighter, but steel boxes offer heavy-duty protection for dual-battery configurations in demanding environments. Consider climate and exposure—marine settings benefit from venting and water resistance.
Ventilation and safety. Boxes with integrated venting protect against gas buildup. Protective covers reduce water intrusion, which helps preserve battery health. For open-air installations on boats or trailers, ensure the design minimizes moisture exposure.
Hardware and mounting. Boxes often include straps, clamps, and pre-drilled holes. If mounting in a tight v-nose area, prioritize models with compact lids and flexible mounting options. Pre-drilled pilot holes simplify direct mounting in some models.
Ease of installation and maintenance. Snap-top or lid designs should allow easy battery access for periodic inspection. Boxes with removable lids or easy-access designs save time during maintenance and battery replacement.
Frequently Asked Questions
- What size battery should I use in a v-nose trailer box? Choose battery group size that matches your trailer’s power needs. Common options include Group 27 for larger systems or two smaller batteries like Group 24 for dual-configurations. Check interior dimensions before purchasing.
- Do these boxes prevent battery acid leaks? Many boxes are made from acid-resistant plastics or coated steel and include venting or protective covers to minimize leakage risk and moisture intrusion.
- Is venting necessary for trailer battery boxes? Yes. Venting reduces hydrogen gas buildup and pressure inside the enclosure, improving safety when batteries are charging or discharging.
- Can I install these boxes myself? Most models are designed for straightforward DIY installation with included hardware and pre-drilled holes. Verify mounting requirements and tool compatibility before starting.
- Which box is best for dual batteries on a v-nose trailer? Dual-battery models with adequate interior space, secure straps, and robust lids (like the Camco 55375 or Peastorm double-box options) are well-suited for dual configurations in constrained spaces.
- Are steel boxes worth the extra weight? Steel boxes offer superior rigidity and protection for heavy or high-vibration installations, but weigh more and may require additional mounting support compared to polymer boxes.
