the 6 Best marine Battery kits (2023 reviews)

We are personally inclined towards taylor cable marine battery kit, it is not so pricy, but it overachieves its purpose and outstanding in important aspects. This single trunk mount battery relocator kit helps provide better weight distribution and traction and reduces engine compartment clutter. It includes everything you need to mount an auxiliary battery, and it has held up pretty well. It's also heavy, but that's just a byproduct of its sturdiness. The included cables are thick gauge and the pre-installed connectors are a nice touch.

The battery tray is coated in a corrosive-resistant, rubbery material that seems like it will add to it's longevity. There is plenty of length on the positive cable to get from the engine bay to the trunk. The cable length provided is more than enough to wire even a long car, and it has held up pretty well. Seriously, this kit has worked well, and is easy to install.
