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.

I am totally off grid 2800 square-foot house after the house is warmed up, Eco Flo, pro extra battery I can run one complete day, the furnace and Full size fridge, lights Fireplace blower and use about 50%. You don’t want to take it down below that because it’s gonna take about four hours to charge it. I have another set Eco Flo pro an extra battery. that I use while the first battery is charging effectively, I could take both batteries down to 20% and live for four days with no charging excellent product remember, you don’t wanna get the system too big it’s gonna take too long to charge you from a generator.

I have the Delta pro and one extra battery at the moment and I'm looking to purchase a second battery. I like everything about the units except what another reviewer said, the cable to hook the extra battery up it's so short the extra batteries have to be on the two sides of the Delta pro power station. I have them in a small laundry room on a shelf and I wanted to put the extra battery on the shelf but since the cable is only 3.2 ft or meter long I can only put one battery on the shelf above the Delta pro power station. So if I want to add another battery it will have to be on the floor right next to the power station for the cable to reach. Unfortunately then my dryer door will not open more than a third. They said I could buy the 16-ft cable with the smart battery adapter which is way too long. Can't we just get a seven or eight foot cable I hear a lot of people with the same issue. I'm sure 16 ft cable plus smart battery adapter isn't cheap either. And then there's 16 feet of cable to have hanging around. That's the only reason I took one star off everything else is great but I'm in a bind hooking up the extra battery with one option, buy 16 ft cable with extra battery adapter. I called EcoFlow they have no intention of making a 8-ft cable or just one that would actually work. The ease of use is very easy but I took a star off because I had to take one off because no one thought of making a cable long enough to stack the batteries. And it's not some cord you just go in the store and buy one.
