Dual Battery Systems
Reliable auxiliary power — engineered for BYD & Denza platforms.
Dual battery systems are the backbone of any serious touring, trade, or remote-work setup. Fridges, lighting, inverters, Starlink, tools and accessories all rely on stable auxiliary power — but on BYD and Denza EV/PHEV platforms, dual battery systems must be designed and installed correctly to avoid faults, warnings, or long-term electrical issues.
At MAKA OFFROAD, we design and install vehicle-specific dual battery systems that work safely alongside high-voltage architecture — from simple touring setups to full Victron-powered systems.

How MAKA Designs Dual Battery Systems (This Is Critical)
Every dual battery system we install is designed from the ground up, not pulled off a shelf.
We assess:
- Power draw of all accessories
- Battery chemistry (AGM vs lithium)
- Charging sources (alternator, DC-DC, solar)
- Mounting location and ventilation
- Weight and payload impact
- Vehicle system compatibility (EV/PHEV considerations)
No overloaded circuits. No guesswork.
Common Dual Battery Setups We Build
- Touring fridge + lighting systems
- Trade vehicle power solutions
- Inverter-based setups for tools and appliances
- Solar-assisted charging systems
- Expandable systems for future upgrades
Each system is built to be safe, serviceable and scalable.
