Camco Double Battery Box – Safely Stores Two Batteries
The Camco 55375 box is built to hold two 6V GC2 batteries or two 12V Group 24/24M units. Its heavy-duty, corrosion-resilient polymer construction helps protect batteries from road dust, moisture, and vibration. Best for RV owners and boaters who need a compact, dual-battery solution that fits standard dimensions in tight spaces. A potential limitation is size compatibility with larger 12V AGM variants, which may require confirmation of battery dimensions before purchase.
Camco Large Battery Box with Straps and Hardware
This large Camco box (55373) is designed for Group 27, 30, and 31 batteries. It includes a lift-off lid, a durable woven hold-down strap, and stainless steel hardware. Its polypropylene construction resists corrosion and weathering, making it a solid choice for longer trips and outdoor storage. Best for users needing a reliable, easy-to-secure enclosure with included mounting hardware. A caution: ensure the internal space suits the exact battery height if upgrading to taller packs.
Attwood 9067-1 Vented Battery Box
The Attwood 9067-1 accommodates Group 27 batteries up to 10.5 inches high. Its acid-resistant polypropylene and integrated ventilation help manage gases while keeping water intrusion to a minimum. This makes it ideal for heavier marine or RV batteries where venting and resilience matter. Choose this if you need a compact, vented enclosure that still offers a precise fit. Limitation: interior dimensions are compact, so verify battery height before purchase.
Newport Vessels Trolling Motor Battery Box Power Center
This medium-sized box acts as a power hub with built-in USB and 12V ports. It’s designed to create a clean, organized setup for kayaks, jon boats, and small watercraft. Best for boaters who want easy external connections without exposed wiring. It is not a pure battery enclosure alone; consider it as an all-in-one power center when you need quick access to electronics in on-water scenarios. A possible limitation is the external ports, which may require a snug fit in tight compartments.
NOCO Snap-Top BG27 Battery Box
The NOCO Snap-Top BG27 offers a rugged, versatile design for Group 27 and similar batteries. It emphasizes a rigid snap-top construction and simplified installation, with pre-drilled holes for direct mounting and an optional strap system for more demanding installs. Best for users who want a straightforward setup without complex wiring. A limitation: its detailed dimensions should be confirmed to ensure fit with taller or non-standard packs.
Peastorm 12V Steel Battery Box (Group 27)
This 12V steel box by Peastorm is designed for Group 27 batteries and offers a robust, weather-resistant solution. It features side handles, a lockable upper cover, rubber-sealed holes, and bottom mounting holes with screws included. Best for users needing enhanced security and durability in rugged environments. Caution: steel boxes are heavier than polymer options, which can affect portability and vehicle load considerations.
Buying Guide
- What size battery fits your system? Check length, width, and height against the box interior to avoid fit issues.
- Material matters. Polymer boxes resist corrosion and are lighter; steel boxes offer increased durability and security but weigh more.
- Ventilation and sealing. For acid batteries, venting and water intrusion protection reduce risks; select models with integrated vents or tight seals.
- Mounting and straps. Look for pre-drilled holes, mounting hardware, and strap systems for secure installation on moving trailers or boats.
- One vs. multiple batteries. If you need two batteries, ensure the interior space accommodates the intended battery types and configurations.
- External access. Boxes with accessible terminals or external connections simplify wiring for trolling motors and electronics.
- Security features. Consider lockable lids or secure fastening if the trailer or vessel stores away from secure locations.

Look for boxes labeled to hold two group size batteries with internal dimensions that fit your specific models, such as 21 1/2″ L x 7 3/8″ W x 11 3/16″ H for the Camco 55375.
Ventilation is important for acid or flooded batteries to release gases; consider vented designs or boxes with protective covers if venting is needed.
Yes, many boxes include mounting hardware and strap systems; ensure compatibility with your trailer frame and weight limits.
Steel boxes provide enhanced rigidity and security but are heavier. Polymer boxes resist corrosion and are typically lighter for easier handling.
All-in-one centers simplify wiring and provide USB/12V access, but if you only need battery protection and basic storage, a standard battery box may suffice.
A compact dual-battery box in polymer (like Camco 55375) often balances fit, weight, and corrosion resistance for tight spaces.
