Custom Dual Battery Relocation Kits

Running dual batteries and looking for a complete solution? No problem! We offer two solutions:

  1. Modify any of our Standard or Deluxe Battery Relocation Kits to allow you to connect the second battery.
  2. Custom design and build a kit to meet your specifications.

In some applications, the batteries can be located next to each other. In other applications, the batteries need to be located on opposite sides of the vehicle. Either way, you can count on us to deliver a kit that will exceed your expectations. No different from our Standard or Deluxe Battery Relocation Kits, our Custom Dual Battery Relocation Kits will include every single thing you need to install them!

Some Examples of Our Work

Jeep Cherokee Dual Battery Relocation Kit

Batteries located next to one another. (Moroso Battery Boxes and split loom tubing not shown.)

Shown here is a kit we built for a Jeep Cherokee with a massive Warn winch. This kit includes dual runs of 1/0 AWG to feed that winch with plenty of power and eliminate the voltage drop that would be associated with a single run of 1/0 AWG.

The dual 1/0 AWG power cables are each protected via 500 Amp fuses and terminate at a custom power distribution center. The power distribution center provides an easy location to connect the winch, starter, and OEM wiring harness. In addition, this customer requested a Master ON/OFF switch so that he could turn off his running Jeep in the event of an emergency when on the trail. We utilized the Moroso 74102 Super Duty Battery Disconnect Switch as it has an instantaneous current rating of 2,000 Amps! Finally, we fabbed up a special exciter disconnect harness to interface with the alternator so that it would stop charging when the switch was turned to the OFF position.

2009 Dodge Diesel Truck Dual Battery Relocation Kit

Batteries located on opposite sides in the rear of the bed. (Moroso Battery Boxes and split loom tubing not shown.)

Apparently, when you make over 900hp and 1400lb-ft of torque in a late model Dodge diesel truck, the aftermarket turbos and plumbing require a substantial amount of real estate!

The owner and builder of this one of a kind Dodge decided to relocate the batteries to the rear of the truck to free as much space as possible in the engine compartment. This truck serves primary duties as a hauler, so the batteries had to be moved to the rear-most corners in the bed to clear the 5th wheel trailer hitch and fuel cell. This necessitated some LONG runs between the 300 Amp Ohio Generator alternator, between each of the batteries, and from the batteries back to the front. The builder provided us detailed specifications and we designed a kit to suit them that can provide some SERIOUS current to start the engine on even the coldest winter day.

  • Single run of 1/0 AWG from Alternator to Batteries, protected via 300 Amp fuse
  • Dual runs of 1/0 AWG between Batteries, each protected via 500 Amp fuses
  • Dual runs of 1/0 AWG between Batteries and Power Distribution Center
  • Custom Power Distribution Center to facilitate simple connections to the starter, intake grid heater, and OEM power / relay center
  • Moroso 74102 Super Duty Battery Disconnect Switch – to pass tech at the local drag strip*
  • 1/0 AWG Ground Cables for batteries, alternator, and engine block
  • 8 AWG Ground Cables for bed, cab, and body
  • Dual Moroso Battery Boxes
  • A complete assortment of Grade 5 Hardware, Adel Clamps, Split Loom Tubing, etc.

*Nothin’ is cooler than a 9,000 pound truck that can run in the 11s in the quarter!
