Product Description
Expandable Capacity
Increase the capacity of DELTA 3 Plus/DELTA 3 with an extra 1024Wh. Double the
capacity to meet your energy storage needs—ideal for home backup, RVing, outdoor
adventures, and everyday use.
Compact Design
1/3 smaller than the power station, but with the same power. It can also be securely
stacked on top of the power station to save space and reduce clutter.
10-Year Lifespan with an LFP Battery
The LFP battery chemistry enables 4000+ complete cycles until it reaches 80%
capacity. That means about 10 years of daily use—6× longer than other power
stations with similar capacity and output.
Easy to Use
A plug-and-play system with no setup required. Simply connect it to your power
station for more energy storage. Use the EcoFlow app to monitor and control the
DELTA 3 Smart Extra Battery with ease.
Control From Anywhere
Get all the details—battery percentage, remaining recharge time, hours left, and
more—right on the built-in screen or from the EcoFlow app, wherever you are.
Convenient Recharging
Recharge the Extra Battery by connecting it to the power station's Extra Battery port.
Use AC outlets, portable solar panels, or the Smart Generator for versatile charging
options.
