Description
Expand your DELTA 3 Max Plus’s capacity at a special offer price with the EcoFlow DELTA 3 Max Plus Smart Extra Battery — the dedicated expansion battery that unlocks the DELTA 3 Max Plus’s full storage potential. Adding this battery significantly increases your total system capacity, extending runtime and giving you more energy reserve for longer outages and multi-day off-grid adventures.
The DELTA 3 Max Plus Smart Extra Battery adds 2,048Wh of LiFePO4 storage to your station via a secure plug-and-play expansion port connection. Once connected, the DELTA 3 Max Plus immediately detects the additional capacity and displays the updated total — no configuration required. The Smart battery designation means active cell monitoring is built in: the battery continuously communicates health, temperature, and state-of-charge data to the station for optimized intelligent charging and long-term battery life management.
Built on LFP chemistry, this battery delivers over 3,000 charge cycles with 80%+ capacity retention — well over a decade of daily use. It charges through the DELTA 3 Max Plus’s charging system, including solar input. The combination of the DELTA 3 Max Plus station and this Smart Extra Battery creates a powerful, highly capable home backup and off-grid energy system at a special offer price that makes the upgrade even more compelling.
Compatible exclusively with EcoFlow DELTA 3 Max Plus. Backed by EcoFlow’s standard product warranty.
