peastorm Group 27 Battery Box — Steel Lockable Enclosure, Black, for Car RV Marine

peastorm's 12V Group 27 steel battery box is a lockable, ventilated relocation kit that secures and organizes a Group 27 battery for car, RV, trailer, marine, or kayak installations.

This assembled-steel battery enclosure is built to protect a single Group 27 battery while making relocation and mounting simpler for vehicles, boats, and outdoor rigs. With a powder-coated black finish, rubber-sealed wiring holes, side handles, bottom mounting points, and a lockable top cover, the kit combines durability with installation convenience. The box ships as a compact kit that you put together in minutes and includes the screws needed to secure it.

How does this battery box protect my battery during travel?

The heavy-gauge steel shell shields the battery from impacts, splashes, and debris, and the black spray coating adds UV and corrosion resistance. The lockable top reduces accidental contact with terminals, while rubber gaskets around wiring holes limit moisture and dust ingress.

• Heavy-duty steel construction for impact resistance
• Powder/spray black coating for UV and rust protection
• Lockable lid to prevent terminal shorts and tampering
• Rubber-ringed wiring holes to keep out moisture and dust

Will my Group 27 battery fit, and what are the exact dimensions?

The enclosure is tailored to Group 27 batteries and lists both internal capacity and external footprint so you can confirm fit before purchase. Measure your battery against the maximum capacity size to ensure proper clearance for cables and mounting hardware.

• Maximum internal capacity: 13.78" L x 7.8" W x 11" H
• External box size: 14" L x 8" W x 11.25" H
• Reserve extra space for terminal connectors and cable routing

What features make installation and use easier?

peastorm designed the box with practical hardware and user-friendly details to speed installation and maintenance. Side handles give a secure grip for placement, pre-drilled bottom holes allow fixed mounting with included screws, and multiple wiring ports let you route cables without cutting the shell.

• Side handles for carrying and positioning
• Pre-drilled bottom mounting holes with screws included
• Multiple sealed ports for neat cable entry and exit
• Quick assembly — approximately 10 minutes

Is this battery box suitable for marine and outdoor use?

The steel construction and protective coating improve weather resistance compared with plain metal boxes, while rubber seals on cable openings help against splashing. It is intended for general outdoor and marine applications, but use appropriate marine-grade cabling and corrosion inhibitors where long-term saltwater exposure occurs.

• Black coated steel helps resist UV and light corrosion
• Sealed wiring holes to reduce water ingress
• Recommended to pair with marine-grade terminals for saltwater environments
