Bus Bars
Adding electrical accessories to your vehicle has never been easier! Devices connected to the bus bars run from the Aux battery and will not drain your cranking battery.
3 sizes of studs for connecting heavy wires like your winch, stereo amps, fuse boxes, etc. Connect smaller ring terminals to the small screws.
Boost Switch
- Auto - Connects the batteries automatically based on their voltage level
- On - Manually connects the batteries together just like jumper cables to help start the engine
- Off - Manually separates the batteries
G Screen Port
Plug in our optional G Screen Monitoring System with a single cable to keep an eye on your system.
How It Works
The heart of the system is a smart battery combiner that handles connecting / disconnecting the batteries automatically.
When the engine starts, it allows the engine to charge the cranking battery first, then links the batteries together in parallel so they can both be charged by the alternator.
Once it sees the voltage drop below ~12.7v for a minute, it will separate the batteries. Your accessories connected to the bus bars continue to run from the second battery and won't drain your cranking battery.
Battery Size Options
Since there is no room under the hood for an extra battery, this kit keeps the stock batteries under the hood, and the new Aux battery is mounted under the back seat. There are several sizes that will fit in our adjustable battery brackets under the back seat. The battery needs to be approx. 6.8" deep. Some commonly used sizes include Group numbers 35, 34R, 94R, and the largest battery that will fit is a Group 27F. The 27F is shown in our installation video and it is a very tight fit. The Group 94R has almost as much capacity as the 27F but it is a little easier to install under the seat, especially on the 392.
Bus Bar Sizes
The Positive and Negative bus bars have 3 different size studs - - 3/8", 5/16", and 1/4" diameter for heavy cables for a winch, air compressor, fuse box, etc, and three #10 screws for attaching smaller ring terminals for your low amp accessories such as small LED lights.
Cable Size
Our battery cables are made with 2ga heavy duty, high strand count, pure copper welding cable. Why welding cable instead of battery cable? It's more flexible, more conductive, with a thicker, more abrasion resistant jacket for ultimate durability. The lugs are made of pure copper and tin plated which is more conductive and eliminates corrosion, then covered with an extra thick, adhesive-lined heat shrink material to fully seal the ends of the copper wire for long lasting performance.
Install Time
If you're handy with a wrench, and if you follow along with our detailed installation video, most people can install this kit in their driveway in 2-3 hours. If you prefer to have your local 4x4 shop install it for you, most shops will bill 2 hours for installation in a stock vehicle. If you already have some aftermarket wiring that needs to be rerouted to our bus bars or otherwise cleaned up, add to the installation time as appropriate.
Compatibility
This kit puts the Power Hub under the hood, mounted on a new bracket over the fuse box.
It will interfere with any other aftermarket device that uses the space on top of the fuse box.
NOTE: It will not fit with the 392 engine because the fuse box sits higher than on the diesel version. So for the 392 JL, the Power Hub MUST go under the back seat.
