Lithium3000 Portable Power Station | Mobile Dual Battery System

The Lithium3000 is Flexopower's largest portable power station — a 2560Wh Mobile Dual Battery System built for serious overlanders, caravan and trailer owners, and anyone who needs high-capacity power for home, office or field use. With a 3000W pure sine AC output, expandable battery capacity up to 17.5kWh, true UPS functionality and built-in solar MPPT, the Lithium3000 is the most capable unit in the Flexopower ecosystem.
Fits perfectly in a trailer or caravan. When the trip is done, remove it and connect it to your home or office. Conveniently movable with an expandable pull handle and wheels.
Mobile Dual Battery System — With the FlexoDrive DC-DC Unit
The Lithium3000 becomes a complete vehicle-based Mobile Dual Battery System when paired with one or two FlexoDrive DC-DC units, installed by a qualified Flexopower installer. Each DC-DC unit delivers 320W of intelligent alternator charging — two units combined deliver 640W while you drive. 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.

Expandable Capacity — Up to 17.5kWh
The Lithium3000 supports up to six additional battery modules — each adding 2.5kWh — bringing total system capacity to 17.5kWh. This makes the Lithium3000 a serious home backup, off-grid cabin or extended expedition power solution.
Additional battery modules are not included and must be purchased separately. Contact us for pricing and availability.
