Lithium700 Portable Power Station | Mobile Dual Battery System
The Lithium700 is Flexopower's compact Mobile Dual Battery System — a 672Wh portable power station built for weekend campers, caravan owners and anyone who needs reliable power beyond the grid without the bulk of a larger unit. Enough capacity to keep a camping fridge running for 24 hours. With a rugged aluminium shell, replaceable LiFePO4 battery, Anderson SB50 DC output and true UPS functionality, the Lithium700 punches well above its size.
For alternator charging while driving, the Lithium700 is compatible with the FlexoDrive DC-DC unit — installed by a qualified installer — giving you a complete vehicle-based Mobile Dual Battery System.
Mobile Dual Battery System — With the FlexoDrive DC-DC Unit
The Lithium700 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 Lithium700 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 Lithium700 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 700W to 900W by reducing operating voltage from 230V to 200V. This allows you to run appliances that exceed the standard 700W 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.

Flexopower Lithium700-SB50 – Bush-Ready Power
I bought the Flexopower Lithium700-SB50 in April and used it for 3 weeks in Namibia. It ran my fridge flawlessly the entire trip. I used to have a dual battery system, but this unit is a dream in the bush — compact, portable, and totally hassle-free. Highly recommended for overlanders.
After picking up a problem with my 700 power station, I contacted Quinton at Flexopower, who advised that they will be replacing the unit with a new one. Ver good outcome and service from the team at Flexopower
