This box is built to withstand the demands of marine, RV, and automotive use.
Installation is a key focus, with NOCO offering multiple mounting options. You can use the pre-drilled internal pilot holes for direct mounting without a strap, or utilize the integrated strap mount system for more rugged and demanding installations where extra security is needed. This flexibility makes it easy to secure your battery in various settings.
usvehj Track Mounted Battery Box for Fish Finders
This battery box is an excellent solution for kayak anglers who use a track system. It is designed as a direct replacement for the YakAttack CellBlok and can be attached to most common kayak track systems. Its compact design fits most 7, 9, or 10 Ah 12v batteries, making it ideal for powering a fish finder without taking up valuable deck space.
The top surface of the box doubles as a mounting platform for your fish finder display or a transducer deployment arm. This integrated approach helps create a clean and organized setup. Installation is tool-free; you simply loosen two track-mount knobs to attach or remove the box, requiring no permanent modifications to your kayak.
YakAttack Switchblade Transducer Mount

Buying Guide: How to Choose a Kayak Battery Box
When I’m getting my kayak ready for a day on the water, the last thing I want to worry about is my battery getting wet or coming loose. A good battery box is non-negotiable. It’s not just a container; it’s a protective case for the heart of your trolling motor or fish finder. Since you’re looking at the 9 best battery boxes for kayaks, let’s talk about what makes one stand out from the rest.
First and foremost, you need to think about waterproofing. This is the whole point. Look for boxes with a solid, rubber gasket in the lid and robust latches that create a solid seal. I always test a new box at home with some paper towels inside—a quick splash in the sink or a spray with a hose will tell you if it’s truly watertight. An IPX rating is a great indicator, with IPX6 or higher being ideal for handling waves and rain.
Next, consider the internal organization. A simple empty box is okay, but the best ones have built-in features to keep everything secure and tidy. Look for molded-in battery trays or straps to hold your battery firmly in place, preventing it from bouncing around. Some boxes also have separate compartments for your charger, fuses, or terminal protectors, which I find incredibly handy. This prevents any metal objects from accidentally shorting the battery terminals.
Durability and material are also key. Most boxes are made from ABS plastic or polypropylene. You want something that can withstand UV rays from the sun, resist impacts from a drop onto the deck, and not become brittle in cold weather. Feel the plastic; a flimsy, thin box is a red flag. Also, check the overall design. A low-profile box is often better for a kayak as it fits more easily in the limited storage space, like a tankwell or between your legs.
Finally, don’t forget about usability. How easy is it to access the battery? Are the cable ports designed well to close tightly around your wires? I prefer boxes with dual cable ports, as this allows for a neater setup for both power and charging. A handle that’s comfortable to carry is a nice bonus, especially when you’re lugging a heavy battery from your car to the kayak. By focusing on these aspects—waterproofing, internal security, durability, and smart features—you’ll find a battery box that gives you peace of mind and keeps your electronics running all day long. Finding one of the 9 best battery boxes for kayaks means finding a reliable partner for your adventures.
Frequently Asked Questions
What size battery box do I need for my kayak?
This is probably the first question I had to answer for myself. The box size is entirely determined by the physical dimensions of your battery. Kayaks typically use Group 24, Group 27, or more commonly, the smaller Group U1 size batteries. Before you buy any box, measure your battery’s length, width, and height. Then, check the internal dimensions of the battery box to ensure it has a little extra room for terminals and wires. A box that’s too tight is a hassle, and one that’s too large lets the battery slide around, which is a safety risk.
Are all kayak battery boxes completely waterproof?
Most quality boxes are marketed as “waterproof,” but there are levels to this. A box with a good silicone or rubber gasket and strong latches will be highly water-resistant, perfect for splashes and rain. However, “submersible” is a different standard. If your kayak were to capsize, a water-resistant box might leak if fully submerged for an extended time. For true peace of mind, look for an IPX rating. IPX7, for example, means the box can be immersed in up to 1 meter of water for 30 minutes. For most kayaking situations, a well-sealed, water-resistant box is perfectly adequate.
Can I charge my battery while it’s inside the box?
Yes, and this is a fantastic feature of a good battery box. Many models come with built-in cable ports—little rubber-sealed holes or flaps that you can run your charger cables through. This allows you to plug in your charger without ever opening the box, maintaining the seal and protecting the battery from the elements. It’s a huge convenience. Just make sure the ports seal tightly around your cables to keep moisture out.
How do I secure the battery box in my kayak?
You don’t want a heavy battery box sliding around your kayak. The best method is to use the existing attachment points in your kayak, like the bungee cords in the tankwell or the D-rings. Many battery boxes have built-in handles or grooves that bungee cords can hook onto. For a more permanent solution, you can use heavy-duty velcro straps or even screw a small pad eye (a stainless-steel loop) onto your kayak’s deck to run a strap through. Always make sure it’s snug and won’t shift during a sharp turn or in choppy water.
What extra features should I look for in a battery box?
Beyond being a simple container, the best battery boxes for kayaks add smart features. I really appreciate built-in battery tie-downs or straps, which are essential for safety. Some boxes include a 12V power port (cigarette lighter style) or USB outlets right on the lid, so you can power your gadgets directly without opening the box. Separate compartments for storing fuses, terminal covers, and tools are also incredibly useful for keeping everything organized and in one place.
Is it safe to mount my fish finder directly to the battery box?
While it might seem convenient, I generally advise against permanently mounting your fish finder display to the battery box itself. The box can shift, and you risk putting stress on the wires and connections. It’s better practice to mount the fish finder to your kayak’s deck or a dedicated arm, and then simply run the power cable to the battery inside the box. This isolates the sensitive electronics from any movement of the heavy battery unit.
