Product Details

The EcoFlow DELTA Pro Smart Extra Battery transforms the DELTA Pro from a capable large-format station into a whole-home backup system — expanding from 3600Wh to 7200Wh with a single connection. Add a second for 10,800Wh: enough for 24+ hours of whole-home essential backup including refrigerators, medical devices, HVAC fans, lighting, and communications.

Each extra battery connects to the DELTA Pro's expansion port and charges simultaneously via any input source — solar, AC, car, or smart generator. With 1600W solar input, the full 7200Wh system recharges in approximately 4.5 hours from EcoFlow 400W panels, while AC wall charging fills the combined system in under 3 hours. The BMS manages charge balancing between the main unit and batteries automatically, with no user configuration required.
