CNRAQR Complete Aluminum Battery Box Relocation Kit
This fully sealed relocation kit is compatible with many vehicle types and includes a bolt-on design for straightforward installation in the back of a car, truck, or trailer. It’s well-suited for boat enthusiasts who need a robust, sealed battery housing that won’t leak or corrode in marine use. Limitation: cable length and kit contents exclude the battery cables.
VEVOR Battery Box, Group 24/31
Designed for marine and off-road use, this aluminum alloy box accommodates lead-acid, lithium, and AGM batteries across 12V/24V/36V configurations. It features strong heat dissipation and corrosion resistance, plus multi-directional wiring holes for flexible installation. Choose this if you require a versatile, durable box that supports multiple battery chemistries. Caution: verify the exact dimensions align with your boat’s battery bay.
CNRAQR Aluminum Battery Box (Group 24)
This Group 24 box mirrors the Group 27 model with a slightly smaller footprint, ideal for boats with tighter storage compartments or smaller trailers. It uses a bolt-in design and a PVC-coated aluminum shell for corrosion resistance. Best for boaters needing a sturdy, compact solution without sacrificing durability. Limitation: slightly smaller capacity than Group 27 equivalents.
CNRAQR Battery Box Relocation Kit Aluminum Universal Trunk Fit
This universal trunk-fit kit comes with lockable latches on both sides, allowing the box to be secured and optionally used as portable storage when not deployed as a battery box.

Buying Guide
What size box fits my boat’s battery?
Measure your battery group (e.g., Group 24, 27) and the available space in your boat. Choose a box with inner dimensions that provide clearance for mounting hardware and ventilation. Group 27 and Group 24 variants are common on marine vessels, but always verify compatibility with your battery model.
What about corrosion resistance and weather sealing?
Look for aluminum shells with protective coatings (PVC or similar) and properly sealed edges to resist salt spray, humidity, and splash. A durable seal or lid helps prevent corrosion and water intrusion that can degrade battery life.
How should I route wiring for a boat application?
Prefer boxes with multiple cable entry points or front/side/bottom access to simplify routing. Plan for cable length, strain relief, and a clear path to your trolling motor or electronics to minimize exposed wiring.
Is portability or fixed installation more important?
Relocation kits with bolt-on designs are ideal for fixed installations, while models with removable armrests or portable features provide flexibility for storage or transport. Consider how often you’ll remove the box from the boat or trailer.
What security considerations matter on a boat?
For boxes installed in exposed locations, choose models with lockable latches or compatible padlocks. Security helps deter theft of batteries and related gear when docked or stored.
What are the practical pros and cons of aluminum vs. other materials?
Aluminum boxes offer strong durability, lighter weight, and good corrosion resistance. They can be more expensive than polymer options but typically provide longer life in marine environments. Ensure the lid sealing and coatings meet marine-grade standards for best performance.
