Great and easy upgrade. Bronco Raptor had to learn a new charging system. Only took a few days. Very happy.

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.
The heavy duty Smart Battery Combiner device is rated to handle 300 amps continuously flowing through it. It can handle higher amperage loads for shorter durations - 500 amps for 5 minutes, and up to 2,000 amps for 5 seconds. The combiner requires a minimum of 8 volts to operate. It does not consume any power to keep the batteries connected together, and it does not generate any heat.
Sold separately. Odyssey ODP-AGM25 batteries fit the best due to the very tight space in the Bronco engine bay. You may be able to use other brands of Group 25 batteries that have straight sides but some cutting of the factory sheet metal may be required. Please see our detailed installation video for more details.
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.
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.
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.

FAQs
How long will it take to get my order?
Our products ship from our office in Olive Branch, MS, just outside of Memphis, TN. We work hard to keep everything in stock for same day shipping on most orders placed by 3pm Central time.

Tracking information will be provided when we create your shipping label.
How can I hook up solar panels?
Most people want to use solar panels to be able to run their accessories for as long as possible with the engine off. You can connect the solar charge controller directly to our power and ground bus bars. The solar charge will go into your aux battery first to replace the power used by your accessories. As long as the panel is big enough to keep up with the demand and charge up the battery, then our smart isolator will link them together, and the solar will flow over to the cranking battery as well
How do I connect a charger to keep both batteries charged?
You can connect a charger to your factory positive wire on the cranking battery and the factory negative wire on the aux battery. This way the trickle charger works just like your alternator - it will charge the cranking battery first for a couple minutes, then the smart isolator links the batteries together to charge the aux battery as well.
I left my headlights/radio/dome lights turned on, and now the engine won't crank. I thought the system would turn off the cranking battery to protect it from getting too low.
The factory positive wire harness feeds power directly to your fuse box, which means all of the factory circuits are powered from your cranking battery. The isolator does not turn off power to the fuse box. It 'isolates' the 2 batteries from each other, to protect your cranking battery from being drained by your aftermarket accessories that you have wired up to the bus bars. If you accidentally drain your cranking battery, that's when you'd use the boost button to jump start yourself from the second battery.
My factory post clamps won't get tight enough on the battery post. It is loose and causing weird electrical issues.
Most factory battery post clamps are made of light duty stamped sheetmetal, and stretch or wear out over time. First, make sure the post clamp is fully seated all the way to the bottom of the battery post. Try loosing up the post clamp nut so it is very loose, then use a large socket and gently tap the clamp down onto the post. Now tighten the clamp nut and see if it is secure. You can also try using a battery post shim, available from your local auto parts store, to fill the gap between the clamp and the post, allowing the clamp to tighten down more securely.
Do I need an sPOD, or is it unnecessary since the kit has the power and ground bus bars for hooking up my accessories?
The sPOD system from www.4x4spod.com is a great compliment to our dual battery system. It allows you to easy add electrical accessories that need a fuse, relay, and a switch. It does have limitations, however, with the amount of current that can be used through any one switch. For example, you can't control a winch with it due to the very high amp draw for the winch. Our bus bars are perfect for connecting accessories that need direct battery power, or for those that come with a wire harness that includes a fuse, relay, and switch.
How do I connect an sPOD system to the dual battery kit?
The sPOD source unit should be connected directly to our power and ground bus bars. This way, anything that you are controlling through the sPOD will get power from the aux battery, and will not drain down your cranking battery.
Do you ship overseas?
Yes, we ship all over the world. We have customers in over 53 countries! Shipping costs will be calculated before you checkout.

Customer Reviews
Overall rating: 5.0 / 5 from 6 reviews.
Fantastic system that works exactly as advertised. Especially happy with the G Screen and the ability to control the system from the cab. The install went pretty well but was quite a tight fit. Great system overall was just what I needed.
It's definitely a tight fit, but the instruction video was super helpful. I really like the idea of having all my accessories (wench, compressor, auto side steps, etc...) on a separate battery. My only challenge was (and this is a tip for others) I dropped several bolts and sockets off my wrench that fell into the engine bay. What a pain to find!! Hahahaha Anyhow, love the clean setup. Wish you offered a senior citizen or first responder discount, because the entire set up is a bit pricey. But as they say, you get what you pay for!! Thanks Genesis, great product!!!
UPDATED W/ IMAGES Andrew C. 8/8/2025 Installation was fairly straight forward. If using AFE charge pipes in a 2.7L, you will need to move things around a bit to get to the screws that hold the top cover. I also had DV8 Gen 1 wheel well liners that also had to be trimmed to accommodate the battery tray and x2 Odyssey AGM 25s. This took me quite a bit of extra time, as I have about 4 light relays, 2 JL Audio amps (using 4awg), AMP power steps, a ARB air compressor in the pocket under the trunk, and the G Screen for the system. So I had to rewire everything and still need to extend the 2 JL audio 4 gauge wires so that they can be drawn from the 2nd battery. Nice thing is, I no longer worry about power! Will probably add a charging system with some solar panels on the roof (or some other charging source method). Just in case I need the extra juice while tailgating. Overall a solid product and a welcomed addition to my 4 door Wildtrak.
Installation was a breeze, and quality was great. Haven't gotten off-road after install, but it'll be great for my overlanding power needs!
