- Power Up at Lower Cost
Double or triple the capacity of your EcoFlow Delta for up to 30% less compared to buying another power station when you add an EcoFlow Delta battery.
A Delta Smart Extra Battery enhances the power of the EcoFlow station you already own. It gives you the freedom to charge your portable power station and increase its output at the same time. Just link the extra battery and watch as they sync their charging and discharging to maintain the battery levels across both units.
Made with advanced LFP battery chemistry, the Delta Pro, Delta 2 Max, and Delta 2 Smart Extra Battery boast a lifespan of 3000 full cycles before diminishing to 80% capacity. This gives you almost a decade of reliable power, even with daily use—SIX TIMES LONGER than similar-capacity power stations.
The Smart Extra Battery has a clear LCD screen on the unit's front that shows all the essential details—output, input, remaining charge, and estimated time left. So you can stay informed and in control.
Need info on the go? The EcoFlow app shows you everything you need to know. Making charging and monitoring the Delta Extra Battery a breeze.
The Delta Smart Extra Batteries have a user-friendly and compact design so you can stack them on top of each other and save space. They are easy to set up and use—just plug it into your power station for more energy storage and power.

FAQ
What makes the Smart Extra Battery "smart"?
The Delta Series Smart Extra Battery can be monitored and controlled remotely via the EcoFlow app, offering convenience and control from a distance.
How fast does the Smart Extra Battery charge?
Charge speed varies based on the chosen method, but it's notably fast. Utilizing MultiCharge achieves a rapid 6500W charge speed, allowing both the Delta Pro and the extra battery to charge in under 2 hours. When using a standard AC wall outlet, expect a full charge in approximately 2.7 hours, assuming the Delta Pro unit is fully charged.
How many extra batteries can I use with a portable power station?
The Delta 2 supports only one extra battery, while the Delta Pro, Delta Max, and Delta 2 Max can support up to two extra batteries.
Can I charge the extra battery without connecting it to a power station?
Yes. Using a Smart Generator allows you to charge an extra battery even when it's not connected to a power station. All other charging methods require it to be connected to a power station.
