Do you want an OGE dual battery system but don't see your specific application? Do you want to save some cash by building your own, super clean system using the same parts we use?  This is the kit you're looking for!

We source all of the highest quality, hard to find parts to cleanly install dual batteries in any vehicle.  Simply mount your batteries using our application specific battery trays, our universal tray (coming soon) or your own solution and complete the job with this kit!  

Kit includes:

  • Blue Sea ML-ACR 500 Amp, dual voltage sensing "smart" relay.  Lifetime warranty.
  • 2x 200A MRBF
  • 20' of 2 AWG Welding Cable - High strand count, super flexible, made in USA cable (twice as thick as the competitors).
  • 8x tinned copper battery lugs (two more than you'll need, everyone makes mistakes)
  • 2x Mil-Spec battery terminals
  • 3M adhesive lined heat shrink, red and black (more pieces than you'll need)
  • Plenty of zip Ties

*Switch and harness not included*

**Please note that to properly install this system, you will need access to a heavy duty crimping tool.  There are inexpensive options all over the Internet... Search for "10 Ton Hydraulic Crimper" on Ebay and look for the yellow handles.  They're everywhere.**
