Electrical rework packages
Three tiers for existing overland builds, from a solid foundation to a full worldwide-expedition system.
Foundation
The strong foundational base for an existing overland build, ready to grow with you.
- Battery-to-battery DC-DC charger (BCDC) charging your auxiliary battery from the alternator
- Dual battery system with the starter and auxiliary batteries isolated and protected
- Battery management and monitoring, with a live state-of-charge readout
- Fused distribution panel with open, labeled circuits ready for accessories
- Correctly sized cable, breakers and terminations, labeled and documented
Trail
Everything in Foundation, plus the power and charging to live off-grid for days.
- Everything in Foundation
- Roof-mounted solar with an MPPT controller feeding the auxiliary battery
- Larger lithium auxiliary battery bank sized to your actual loads
- Dedicated 12V fridge circuit plus switched circuits for lighting, USB and accessories
- Inverter for 120V AC when you need it
Expedition
A complete electrical rework, built and proven for a worldwide overland trip.
- Everything in Trail, sized up for extended remote travel
- Redundant charging from the alternator (BCDC), solar and shore power, so one failure never strands you
- Remote battery and system monitoring with fault alerts
- Full harness rebuild with protected, serviceable routing, plus a spare fuse and parts kit
- Load-tested and documented before you leave, with wiring diagram and owner's guide
