This single trunk mount battery relocator kit helps provide better weight distribution and traction and reduces engine compartment clutter. It includes a 16-ft red 2-gauge cable that goes from the battery to the starter, a 20� black 2-gauge cable from the battery to the ground, 3/8� J-bolts, and heavy-duty battery hold downs.
I like the Taylor Cable relocator kit; it includes everything you need to mount an auxiliary battery. The battery tray is large enough to accept most 12v automotive batteries - 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. I use this kit to install a second battery in the trunk of my car, and i didn't need to buy anything else, except the second battery of course.
