For 4×4 owners who spend time off the beaten track, a reliable dual-battery setup is essential. 

Custom Lithium dual-battery systems are designed to provide independent, high-capacity power for your vehicle’s accessories while keeping the starter battery fully charged and ready to go. These systems are particularly useful for powering fridges, lights, winches, water pumps, and other gear on extended trips or off-grid adventures.

Custom Lithium offers vehicle-specific dual-battery systems for a wide range of popular 4x4s, including:

  • Ford Everest and Ranger
  • Isuzu MU-X and D-MAX
  • Jeep Gladiator
  • Nissan Navara NP300 and Patrol Y62
  • Toyota HiLux (N70 and N80)
  • Toyota LandCruiser 79
  • VW Amarok
  • Mazda BT-50

Each system is designed for easy integration with the vehicle’s existing electrical setup and comes with LiFePO₄ lithium batteries for lightweight, high-capacity power. Integrated Battery Management Systems (BMS) ensure protection against overcharging, over-discharging, and overheating, keeping both batteries safe and reliable in remote conditions.

Compared with standard lead-acid dual-battery setups, Custom Lithium systems offer more usable energy, longer lifespan, and consistent voltage output. The lithium batteries maintain steady power for accessories throughout the trip, reducing the risk of running out of energy for critical equipment.

For off-road enthusiasts and overlanders, these dual-battery systems provide a turnkey solution to power camping fridges, lights, and other accessories, while ensuring the starter battery is always ready to start the engine. Vehicle-specific designs make installation straightforward and maximise space efficiency within the engine bay or tray.

With Custom Lithium dual-battery systems, your 4×4 setup can handle extended off-grid trips with reliable, long-lasting power for all your accessories.
