Description
This isn’t just another battery tray and a box of wiring—it’s the most comprehensive DIY dual battery kit on the market for the Toyota LandCruiser 300 Series. Every major component has been carefully designed, tested, pre-mounted, pre-wired, fused, labelled and terminated by our experienced auto electricians, giving you a complete, vehicle-specific power system that installs neatly under the bonnet without sacrificing any interior or cargo space. At the heart of the system is the advanced REDARC Alpha BCDC charger, providing intelligent alternator and solar charging, Bluetooth monitoring, adjustable input control, automatic start-battery maintenance and the ability to recover a flat start battery with the push of a button in as little as 15 minutes. The kit also includes our custom Australian-made battery tray and charger bracket, a vehicle-specific heavy-duty charge harness, your choice of Invicta Xero under-bonnet lithium battery, integrated solar input and a passenger-side rear socket bank for conveniently powering your fridge and accessories. There’s no need to source individual components, work out cable sizes, fabricate brackets or decipher a complicated wiring diagram—everything has been engineered to work together as one complete system. Designed, manufactured and assembled by Accelerate on the Sunshine Coast, this premium kit delivers the finish, reliability and performance of a professionally installed auto-electrical system in a genuinely DIY-friendly package, making it the ultimate power upgrade for LC300 owners who want the very best for touring, towing and off-grid travel.

What’s Included
- Custom laser-cut aluminium battery tray (under-bonnet installation)
- Custom laser-cut aluminium BCDC bracket
- REDARC Alpha BCDC charger (25A or 50A – pre-mounted on BCDC Bracket)
- Choice of solar input (through grille or under bonnet)
- Invicta lithium battery (if selected)
- Vehicle-specific charge harness pre-wired and pre-terminated

Solar Input Options (Important for GR Sport Owners)
This system includes a RED Anderson solar input plug mounted on the front of the BCDC bracket for easy solar connection on standard 300 Series grilles.
If you have a GR Sport with the honeycomb grille, the front-mounted solar plug cannot be used due to grille clearance issues.
Instead, we will supply a dedicated under-bonnet solar mounting bracket so you can still run portable solar panels safely and cleanly.
