EcoFlow DELTA 2 Max Smart Extra Battery 2048Wh, LiFePO4 Extra Battery, Expandable Home Backup Battery – EF-DELTA-Max200-EB

Product details

Expand your energy storage with the EcoFlow DELTA 2 Max Smart Extra Battery. Designed to provide an additional 2,048Wh of battery capacity, it is an ideal solution for users who need longer backup runtime without replacing their existing EcoFlow power station.

The Smart Extra Battery uses LiFePO4 (LFP) battery chemistry and is rated for 3,000 complete cycles before reaching 80%+ of its original capacity, providing long-term energy storage for daily use, home backup, RVing, camping and other applications. EcoFlow describes this as approximately 10 years of daily use under its stated conditions.

The battery is designed for simple plug-and-play expansion. Connect it to a compatible EcoFlow power station and the additional capacity becomes available without complicated installation. The battery can also be monitored and controlled through the EcoFlow app.

When paired with a DELTA 2 Max, users can connect up to two compatible Smart Extra Batteries, increasing the system’s total capacity from 2,048Wh to as much as 6,144Wh (6.144kWh). This makes the system suitable for extended home backup, RV use, outdoor activities and everyday energy storage.

Its stackable design allows the extra battery to be placed securely with compatible EcoFlow equipment, helping save space and keep the setup organized.
