EcoFlow DELTA 3 Smart Extra Battery

Expand your power station’s capacity – quickly, safely, and seamlessly.

The EcoFlow DELTA 3 Smart Extra Battery gives you the perfect way to scale your energy storage. It adds 1 024 Wh of capacity and is designed to stack with the DELTA 3 (or compatible EcoFlow models) via plug-and-play simplicity.

With advanced LFP battery chemistry delivering 4 000+ full cycles (approx. 10 years of daily use), you’ll have reliable energy for home backup, RVs, off-grid adventures, and more. 


 Key Benefits

Capacity Expansion: Add 1 024 Wh to your DELTA 3 system — double your runtime without replacing the base unit. 

Long-Life LFP Battery: Built to last — upwards of 4 000 cycles until 80% capacity. 

Compact & Easy to Use: 1/3 smaller than the previous generation Extra Battery, stackable design, no complicated setup required. 

Smart Monitoring & Control: Use the EcoFlow app to check battery status, remaining time, input/output power, and more remotely. 

Versatile Recharge Options: Recharge via the main unit’s Extra Battery port using AC, solar panels, or the smart generator. 

Ideal For

Home backup during power outages

RVs, motorhomes or mobile/off-grid living

Outdoor adventures and camping

Users who want expandable, long-life energy storage
