FLEXOPOWER'S LITHIUM1200 POWER STATION WITH ANDERSON SB50 GREY DC OUTPUT
The Lithium1200 is Flexopower's best-selling Mobile Dual Battery System — a 1008Wh portable power station built for overlanders, campers, caravan owners and anyone who needs reliable power beyond the grid. With a rugged aluminium shell, replaceable LiFePO4 battery, Anderson SB50 DC output and true UPS functionality, the Lithium1200 is designed to work as hard as you do.
For alternator charging while driving, the Lithium1200 is compatible with the FlexoDrive DC-DC unit — installed by a qualified installer — giving you a complete vehicle-based Mobile Dual Battery System.
Why Choose the Lithium1200
The Lithium1200 is ideal for customers who want:
- A proven, field-tested mobile power system for camping and overlanding
- Anderson SB50 DC output for high-current, low-resistance DC loads
- A replaceable battery — swap it at end of service life without replacing the unit
- True UPS functionality for seamless power transfer during load shedding
- Solar charging via integrated MPPT — plug and play, no controller needed
- A rugged aluminium shell that handles knocks, drops and demanding environments
Mobile Dual Battery System — With the FlexoDrive DC-DC Unit
The Lithium1200 becomes a complete vehicle-based Mobile Dual Battery System when paired with the FlexoDrive DC-DC unit, installed by a qualified Flexopower installer. The DC-DC unit manages alternator charging intelligently at 320W — protecting your vehicle's battery while delivering consistent charge to the Lithium1200 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 FlexoApp.
Unlike a fixed dual-battery installation, the Lithium1200 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.

Power Boost
Power Boost extends the AC output from 1200W to 1600W by reducing operating voltage from 230V to 200V. This allows you to run appliances that exceed the standard 1200W output limit.
Important: appliances with built-in voltage protection are not compatible with Power Boost. Power Boost is always active except when the unit is charging from AC.
