Genesis Offroad Gen 3 Dual Battery Kit

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.

Smart Combiner Specs:

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.

Battery Size Required:

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.

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:

Fits all engine options and all trim levels for the new Bronco.
NOTE: Space is very limited! We HIGHLY RECOMMEND using the Odyssey Group 25 batteries because the case tapers down smaller at the bottom, which allows it to fit tighter towards the fender with NO MODIFICATIONS. If you choose to use another brand of battery, be aware that most brands have straight sides (not tapered at the bottom) and you will need to cut a notch into the factory sheet metal at the front corner to allow the battery to clear the engine
