Kalahari Expedition Pro System | Lithium3000 + Extra Battery + 2x Kalahari400W + 20m FlexoLink + Bracket
The Kalahari Expedition Pro System is Flexopower's most powerful complete mobile energy configuration — the Lithium3000 with an additional 2.5kWh battery module and two Kalahari400W solar panels. 5120Wh of total battery capacity. 800W of solar input. Built for serious overlanders, extended expeditions, off-grid living and fleet operators who cannot compromise on power autonomy.
Park in the shade. Put both panels in the sun. The 20m FlexoLink cable gives you the flexibility to position your solar panels for maximum harvest while keeping your power station cool and protected.
What's in the Kit
- Lithium3000 Portable Power Station — 2560Wh base capacity, expandable. 3000W pure sine AC output, Anderson PP30 30A DC output, true UPS 14ms, integrated solar MPPT, app-enabled.
- Additional 2.5kWh Battery Module — doubles the Lithium3000's base capacity to 5120Wh total — approximately 400Ah equivalent.
- 2 x Kalahari400W Portable Solar Panel — Teflon ETFE encapsulated, shingled solar cell technology, aluminium frame, tilt legs. 800W combined solar input.
- 2 x FlexoLink 20m Extension Cable — Red/Black 4mm² Anderson SB50 grey connectors. One cable per panel.
- Vehicle Mounting Bracket — Custom-designed to secure the Lithium3000 in your vehicle, trailer or canopy during transport. Built for corrugated 4x4 terrain.
Mobile Dual Battery System — With Two FlexoDrive DC-DC Units
The Lithium3000 supports up to two FlexoDrive DC-DC units simultaneously — delivering 640W of combined alternator charging while you drive. Each unit is installed by a qualified Flexopower installer. Engine On / Off Auto Sense detects when the engine starts and stops, automatically beginning and ending the charge cycle without any manual intervention. Monitor and control the system via the app.
Unlike a fixed dual-battery installation, the Lithium3000 moves with you — between vehicles, trailers, camp and home. Your power investment is not locked into one vehicle.
The FlexoDrive DC-DC unit is available through our qualified installer network only — not sold direct. Contact us to find a Flexopower installer near you.
