IN STOCK. SHIPS WITHIN 1 BUSINESS DAY
Looking for the most complete, reliable, efficient, dual battery system for your Toyota 4Runner? This is it
We pride ourselves on providing the most inclusive kits in the industry for a trouble-free installation. This kit requires cutting your own wire and crimping on the ends. For an additional charge, we offer a pre-wire service. If you would like your kit pre-wired and labeled for an even easier installation, please click HERE to add the service to your cart.
This dual battery system features a DC to DC battery charger from REDARC Electronics. These are onboard battery chargers that will charge and maintain your auxiliary battery to a 100% state of charge, unlike many other dual battery kits. With DC to DC charging technology, there is no need to have matching batteries in your system. Feel free to keep your factory starting battery and add a high-quality AGM, Gel, deep cycle flooded, or even Lithium battery as your auxiliary! (We strongly recommend AGM under the hood). As an added bonus, these units are solar-ready! With a built-in MPPT solar charge controller, adding a solar panel to your setup is plug-and-play.
Recommended Auxiliary Battery: Group 34R in both locations ( Odyssey PC1500 Group 34R)

The REDARC BCDC1225D In-vehicle Dual Battery Charger is a 12 volt, 25A in-vehicle DC-DC battery charger designed to charge your secondary battery banks to 100% state of charge while on the move.
