Dual Battery Systems for the BYD Shark 6.
Reliable off-grid power — installed right on a PHEV
A dual battery system on a BYD Shark 6 is one of the most technically complex fitments available, and one of the most important to get right. The BYD Shark 6's PHEV electrical system manages its 12V battery differently to a conventional vehicle, and a dual battery setup that isn't correctly integrated can interfere with that cycle.
MAKA's team is certified in EV and PHEV electrical systems from 12V through 440V. We design, specify, and install dual battery systems that work with the BYD Shark 6's electrical architecture, not around it.

How MAKA Designs and Installs Dual Battery Systems
We don’t install a standard dual battery setup and hope for the best. On a BYD Shark 6, the system needs to be sized for your actual load requirements, the DC-DC charger needs to be compatible with the vehicle’s charge profile, and all connections need to be made so the factory energy management system can operate correctly.
Every dual battery fitment starts with a load calculation and a system design, then we build and install it properly.
Load calculation before any system is specified
DC-DC charger selected for BYD Shark 6 PHEV charge profile compatibility
Clean installation, no improvised connections, no exposed wiring
Full system test under load before handover
Expandable for solar, inverter, and additional loads

Frequently Asked Questions
Do you install dual battery systems in PHEV vehicles?
Yes, and it is one of the more involved jobs on any PHEV. The electrical architecture needs careful integration so the factory system is left alone, and that applies equally across the BYD Shark 6, Denza, Toyota, GWM (Great Wall) and Volkswagen PHEV range. Our team is certified on EV and PHEV systems from 12V through to 440V high voltage components. We size, specify and install dual battery setups that work with your vehicle, not around it.
Which dual battery brands do you stock?
We stock REDARC, Victron, Enerdrive, and Custom Lithium systems, sized to genuine off-grid requirements rather than a one-size-fits-all setup.
Can a dual battery system be added to a full build package?
Yes, dual battery systems feature in touring-focused packages like The Tourer and The Everything, and can be added to any other package or fitted on their own.
Where are your dual battery systems fitted?
Fitment is done at our Baringa, Queensland workshop, where our technicians work across the full PHEV and EV electrical spectrum, from 12V accessory circuits through to high voltage components.
Can I get a dual battery system fitted alongside other accessories?
Yes, dual battery setups are commonly fitted alongside a fridge, drawer system, or long-range fuel and water solutions. Let us know the full picture and we’ll plan it as one integrated system.
