The belief that more is better is often applied to the 4x4 market as builders attempt to create the most efficiently running rig on the trail. Bigger engines, bigger axles, and all the accessories you can imagine are great assets to any 4x4, but there are drawbacks to building a vehicle beyond its limitations. One area that's often overlooked in this procession of aftermarket parts is the addition of multiple electrical accessories. Mate that winch with the extra lighting, an air compressor, the radios, the 12-volt refrigerator, and whatever else you can think of to wire in, and that single-battery setup begins to feel the hurt. One method of koshering such a situation is installing a second battery to shoulder the extra load. Desiring this type of setup for our '01 Jeep TJ, we approached Kilby Enterprises in Burbank, California, to achieve the extra spark needed to drive our power-hungry rig.
Offering a number of Jeep and 4x4 products ranging from onboard air systems to skidplates, Kilby Enterprises has designed a foolproof dual-battery setup for '97-and-newer Jeep TJs. The dual battery kit is designed to use two Optima batteries and offers a quick and easy installation. The kit includes a powdercoated steel battery tray, battery terminals, a battery hold-down strap, and a custom aluminum A/C line. The A/C line is the magic behind the kit as it enables the repositioning of the A/C accumulator to create ample space for the new tray and second battery. In order to link the two batteries and effectively monitor and maintain a sufficient charge, we also installed a relay and cable kit from Wrangler Northwest Power Products.
If you're of the "more is better" school of thought, chances are your rig is ready for a dual battery system. It's an excellent means of gaining an extra charge for those long days of winching on the trail, or if you need to jump-start your own or a buddy's vehicle. It's peace of mind, friends, and Kilby Enterprises offers it in more ways than one.
