Expansion Battery · 3,600Wh
Power up anywhere, anytime
Harness the convenience of DELTA Pro’s Smart Extra Battery, equipped with all the charging capabilities of the DELTA Pro itself, including the powerful 6500W MultiCharge feature. With this innovation, charging becomes a breeze, wherever you may roam, as long as your extra battery remains tethered to the DELTA Pro. Together, they synchronize seamlessly, ensuring consistent battery levels across both units.
Be prepared for any contingency
In moments of adversity, when traditional charging methods falter, rely on the 1800W DC fast charge capability of the EcoFlow Smart Generator (available separately). Simply connect the generator directly to your extra battery via the designated port, even if it's disconnected from the DELTA Pro.
Stay informed and in control
The Smart Extra Battery boasts a vibrant LCD screen on its front facade, providing comprehensive data at a glance: output, input, remaining charge, and estimated time until depletion. For on-the-go insights, the EcoFlow app offers a wealth of information and management options, ensuring you're always in the loop.
Long-lasting power with LFP technology
Featuring advanced LFP battery chemistry, the DELTA Pro Smart Extra Battery offers an impressive lifespan of 3000 complete cycles before capacity diminishes to 80%. This translates to roughly a decade of reliable power, even under daily use—a longevity six times greater than comparable power stations.
Effortless operation
No intricate setup required—simply plug the Smart Extra Battery into your power station for expanded energy storage. Utilizing the intuitive EcoFlow app, charging and monitoring your extra battery becomes a seamless and user-friendly experience.
