Blaze Off-Road Dual Battery System for 4Runner (2010-2024)

Upgrade your 5th Gen build with the Blaze Off-Road Dual Battery System for Toyota 4Runner (2010-2024), a complete solution designed to simplify one of the most important upgrades for overland and off-road vehicles. Traditionally, dual battery systems required either outdated relay-style isolators or complex DC-DC chargers that demanded professional installation. Blaze Off-Road changes that by pairing their vehicle-specific mounting system with the new Redarc BCDC Alpha platform to create a much more installer-friendly solution.

This kit is designed as a complete drop-in foundation that gives you everything needed to add a second battery for powering accessories, camping equipment, lighting, fridges, communications gear, and more — all while protecting your primary starting battery.
