Description
Unlock the full storage potential of your EcoFlow DELTA 3 Max Plus with the dedicated Smart Extra Battery — adding 2,048Wh of LiFePO4 storage via a simple plug-and-play connection that instantly doubles your station’s base capacity. For home backup, extended off-grid trips, or any situation where more energy reserve matters, this battery is the most direct upgrade path for your DELTA 3 Max Plus system.
The 2,048Wh Smart Extra Battery attaches to the DELTA 3 Max Plus’s expansion port and is immediately auto-detected — no app configuration, no manual setup. The station’s display and EcoFlow app update in real time to show the new total capacity. The “Smart” designation means active cell-level monitoring: the battery continuously communicates temperature, voltage, and state-of-charge data to the station for intelligent charge management that optimizes both daily performance and long-term battery health.
Built on LFP chemistry, the battery delivers over 3,000 charge cycles with 80%+ capacity retention — more than a decade of daily use. It charges through the DELTA 3 Max Plus’s charging system, including solar input via the station’s solar port. With the DELTA 3 Max Plus at 2,048Wh base and this Smart Extra Battery added, total combined capacity reaches 4,096Wh — enough for a full day of home essential backup or multiple days of moderate off-grid use.
Compatible exclusively with EcoFlow DELTA 3 Max Plus. Backed by EcoFlow’s standard product warranty.
