Description

Take the guesswork out of installing a 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 kit has been engineered to deliver the clean fit, dependable performance and professional finish you would expect from a premium auto-electrical installation—without sacrificing any cabin or cargo space. Whether you’re powering a fridge, camp lighting, communications equipment or essential 12V accessories, it provides reliable off-grid power in a package designed specifically around the Prado 250.

Every kit is supplied with the major electrical components pre-mounted and pre-wired using premium automotive cabling 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 together through pre-terminated connections, giving you a streamlined installation with no cutting or splicing into the vehicle’s factory wiring.

Unlike a collection of universal parts, every major bracket has been designed 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 vehicle-specific behind-grille charger bracket positions the REDARC Classic 25A BCDC charger away from engine-bay heat for improved airflow, convenient solar access and a clean OEM-style finish. Each metal component is finished in a durable textured black powder coat and supplied with the required mounting hardware.

At the heart of the system is the proven REDARC Classic 25A BCDC charger, providing intelligent charging from the vehicle’s smart alternator and portable solar through its built-in MPPT regulator. Green Power Priority™ makes the most of available solar energy before drawing from the alternator, while REDARC’s multi-stage charging profile safely and efficiently maintains the selected lithium battery. The kit also includes your choice of passenger-side rear socket bank, giving you convenient access to USB charging, 12V power, Anderson outputs or an Engel fridge connection inside the vehicle. Designed, manufactured and assembled by Accelerate Off-Grid Touring on the Sunshine Coast, this is a genuinely complete Prado 250 dual battery system—engineered so every component fits, connects and works together from the moment it arrives.
