Vehicle-specific charge harness – Designed specifically for the LC300 for perfect fitment with no cutting or splicing.

Heavy-duty 6 B&S cabling – Ensures efficient charging of lithium dual battery systems while you drive, covered in self-winding sheathing.

Custom battery tray & BCDC bracket – Laser-cut aluminium, powder-coated matte black for durability and a clean look.

Designed and built by Accelerate – Proudly engineered and tested on the Sunshine Coast for Australian touring conditions.

What’s Included

• Custom laser-cut aluminium battery tray (under-bonnet installation)
• Custom laser-cut aluminium BCDC bracket
• REDARC Classic BCDC charger (25A or 40A – 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 
• Accelerate socket bank of your choice (rear cupholder mount)
• All mounting hardware

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.
