Dual Battery - Prado 250 Series - Under Bonnet - Jumpstart Feature

Take the guesswork out of installing a premium dual battery system with one of the most comprehensive DIY power solutions available for the Toyota LandCruiser Prado 250 Series. Developed over months of design, test fitting and real-world refinement, this complete under-bonnet system delivers the finish and performance of a professional auto-electrical installation without sacrificing any cabin or cargo space. From weekend camping to extended touring, it gives you dependable power for your fridge, lighting, communications equipment and other essential 12V accessories—all from a system purpose-built for your vehicle.

Every kit is supplied with the major components pre-mounted and pre-wired using premium automotive cable and protective sheathing. The wiring is cut to length, terminated, fused and clearly labelled, removing the need to calculate cable sizes, source individual components, crimp heavy-duty terminals or design the system yourself. Our vehicle-specific charge harness connects the start battery, auxiliary battery and BCDC charger through pre-terminated connections, providing a streamlined installation with no cutting or splicing into the vehicle’s factory wiring.

Every bracket has been engineered specifically for the Prado 250 Series. Our custom under-bonnet battery tray replaces the factory start-battery tray while securely retaining the original start battery and creating space for an Invicta Xero lithium auxiliary battery. A dedicated fuel-filter relocation bracket correctly repositions the factory fuel filter, while our behind-grille charger bracket mounts the REDARC Alpha away from engine-bay heat for improved airflow and easy access. Each component is finished in a durable textured black powder coat and supplied with the required mounting hardware for a clean, factory-style result.

At the heart of the system is the advanced REDARC Alpha 25A BCDC charger, delivering far more than conventional DC-DC charging. In addition to intelligent alternator and solar charging, the Alpha provides Bluetooth monitoring and control through the REDARC RedVision app, Green Power Priority™, adjustable input-current limits, wireless firmware updates and automatic start-battery maintenance when surplus solar power is available. If your start battery becomes flat, the system can direct charge back into it at the push of a button, helping recover enough power to start the vehicle in as little as 15 minutes.

The kit also includes your choice of passenger-side rear socket bank, providing convenient access to USB charging, 12V power, Anderson outputs or an Engel fridge connection from inside the vehicle. Designed, manufactured and assembled by Accelerate Off-Grid Touring on the Sunshine Coast, this is not simply a collection of components—it is a complete, premium Prado 250 power system in which every tray, bracket, cable and connection has been engineered to fit and work together from the moment it arrives.
