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 Traditionally, dual battery systems required either outdated relay-style isolators or complex DC-DC chargers that demanded professional installation.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.

Features

  • Designed for Toyota 4Runner (2010-2024): Engineered specifically for 5th Gen 4Runner engine bay fitment.
  • Complete Dual Battery Solution: Includes the major components required to properly add a secondary battery system.
  • Redarc BCDC Alpha 50A DC-DC Charger Included: Provides smart charging and battery management for reliable power distribution.
  • Vehicle Specific Mounting Brackets: Blaze Off-Road brackets ensure proper fitment and secure installation.
  • Pre-Designed Cable System: Includes Blaze Off-Road dual battery cables sized and designed for proper installation.
  • Complete Fuse & Hardware Kit: Includes necessary fuse protection and mounting hardware for safe operation.
  • Supports Overland Electrical Needs: Perfect for powering fridges, lighting, radios, compressors, and camp accessories.
  • DIY Friendly Design: Designed so experienced DIY installers can complete installation without advanced fabrication.
  • Expandable Electrical Foundation: Perfect starting point for full overland electrical builds.

  • Blaze Off-Road vehicle specific dual battery bracket system
  • Redarc BCDC Alpha 50 Amp DC-DC charger
  • Blaze Off-Road BCDC Alpha under-hood mounting bracket
  • Blaze Off-Road dual battery cable kit for required connections

  • Technical support is available directly from Blaze Off-Road if needed

Adding a dual battery system allows you to:

  • Run accessories without draining your starting battery
