Description
Expand your EcoFlow DELTA Pro’s capacity at a special offer price with the EcoFlow DELTA Pro Smart Extra Battery. Each battery adds 3,600Wh of LiFePO4 storage to your DELTA Pro — doubling its base 3,600Wh capacity to 7,200Wh with one battery, or tripling it to up to 25kWh when combining multiple batteries. This special offer makes the DELTA Pro Smart Extra Battery one of the most cost-effective ways to add serious home backup capacity to your existing system.
The Smart Extra Battery connects to the DELTA Pro’s expansion port via a plug-and-play connection, automatically detected and immediately reflected in the station’s display and EcoFlow app. No configuration, no setup — just connect and your DELTA Pro shows the new expanded capacity. The “Smart” designation refers to the battery’s active cell monitoring system, which continuously communicates cell temperature, voltage, and state of charge data to the DELTA Pro for intelligent charge management and long-term health optimization.
Built on LFP chemistry, the DELTA Pro Smart Extra Battery delivers over 3,000 charge cycles — over a decade of daily use — with the superior thermal stability and safety advantages that LFP chemistry is known for. It charges via the DELTA Pro’s charging system, including solar charging through the station’s solar input port. With one or more Smart Extra Batteries, the DELTA Pro becomes a serious whole-home backup system capable of powering essential circuits for an entire day or more.
Compatible exclusively with EcoFlow DELTA Pro. Backed by EcoFlow’s standard product warranty.
