Toyota LandCruiser 300 Series Under-Bonnet Dual Battery Kit with Start Battery Charging
Designed for a clean, factory-style power upgrade, the Toyota LandCruiser 300 Series Under-Bonnet Dual Battery Kit delivers reliable off-grid performance without sacrificing interior or cargo space. Purpose-built for the LC300 platform, this plug-and-play system integrates seamlessly under the bonnet while maintaining a tidy OEM-style finish.
Featuring the advanced REDARC Alpha BCDC charger, this system provides intelligent charging, start battery support, solar prioritisation, and Bluetooth monitoring — giving you complete control over your touring power setup.
Add the Isolated Anderson Plug for caravan charging, ESC power for your van, or a Tow-Pro and trailer bracket for a complete towing and power solution.

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.
