peastorm Group 27 Steel Battery Box — 12V Waterproof Lockable Case (Black) with Rubber Grommets

Peastorm's Group 27 steel battery box is a lockable, waterproof 12V relocation kit built to protect and mount a single Group 27 battery in boats, RVs, trailers, and camping rigs.

This heavy-duty steel enclosure keeps your battery secure from water, sun and movement while providing tidy cable routing and ready mounting points. Designed specifically to fit Group 27 batteries, the box ships with rubber grommets, a lock, and mounting screws so you can install it quickly and minimize corrosion and vibration during travel or on-water use.

How does this battery box protect my battery on a boat or RV?

The Peastorm steel case uses a powder-like black surface finish and steel construction to resist sunlight, splashes and road grime. A lockable lid and included rubber grommets for cable passages reduce moisture intrusion while keeping terminals out of reach.

• Steel shell with durable spray coating for weather resistance
• Lockable top cover with padlock included for security
• Rubber-sealed cable holes to slow water ingress and chafe
• Mounting holes and supplied screws to secure the box against vibration

Will my Group 27 battery fit and how big is the box?

The enclosure is tailored for Group 27 batteries; check your battery's dimensions before buying. The interior accepts batteries up to 13.78" long by 7.8" wide by 11" high, with external box dimensions slightly larger to accommodate the lid and seals.

• Maximum internal capacity: 13.78" L × 7.8" W × 11" H
• External footprint: 14" L × 8" W × 11.25" H
• Designed for a snug fit to limit movement during transport

What installation and connection options does the kit provide?

The kit arrives ready to mount: the bottom includes pre-drilled fixing points with screws, and the lid has multiple reserved holes protected by rubber rings for cable routing. Side handles make positioning easier and the lock helps keep the lid closed under road or water conditions.

• Four bottom fixing holes and included screws for secure mounting
• Multiple top and side reserved holes, each fitted with rubber grommets
• Handles on both sides for easier lifting and placement
• One padlock included to secure the cover during transit

Is the box suitable for saltwater, camping, and trailer use?

Yes — the coated steel construction and sealed passages make it a practical choice across marine, RV and trailer environments. While steel offers strong impact protection, routine inspection and occasional maintenance will extend service life, especially in corrosive saltwater conditions.

• Works for marine trolling motors, RV house batteries, trailers, and camping setups
• Coated finish resists sun and light moisture exposure
• Recommended to rinse and dry after heavy saltwater exposure and inspect seals periodically
