More Stored Energy for Your DELTA Pro 3 System
The EcoFlow DELTA Pro 3 Smart Extra Battery expands the energy storage capacity of a compatible DELTA Pro 3 system by an additional 4,096Wh (4.096kWh), providing longer runtime for home backup, off-grid power, and other high-demand applications.
Built with long-lasting LiFePO₄ (LFP) battery chemistry, the Smart Extra Battery is designed for approximately 4,000 cycles before reaching 80% of its original capacity. Its integrated design allows it to connect directly with the DELTA Pro 3 without requiring a separate inverter or power station.
A DELTA Pro 3 begins with 4.096kWh of storage and can be expanded with additional battery capacity, allowing homeowners to build a larger backup system as their power requirements grow.
The Smart Extra Battery is particularly useful for extending runtime during longer outages, increasing overnight energy reserves, or adding storage to systems incorporating solar charging.
