Product description

The EcoFlow DELTA Pro Additional Battery (1ECO3603, EU) expands the capacity of the DELTA Pro power station up to 10.8 kWh, providing long-lasting, scalable energy storage with smart monitoring and a 5-year warranty.

The EcoFlow DELTA Pro Additional Battery is designed to significantly expand the energy capacity of your EcoFlow DELTA Pro power station. By connecting one additional battery, the total capacity increases from 3.6 kWh to 7.2 kWh, while connecting two units boosts capacity up to an impressive 10.8 kWh. Once connected, the system ensures simultaneous and balanced charging and discharging across the station and all additional batteries, maximizing efficiency and battery lifespan.

This additional battery fully supports EcoFlow’s MultiCharge technology, allowing flexible charging from solar panels, AC outlets, or EV charging stations anytime and anywhere. Equipped with a clear front-facing LCD display, it provides real-time information on battery status, input/output power, remaining capacity, and time to full charge. For added convenience, monitoring and control are also available via the EcoFlow mobile application. Built using durable LFP battery technology and backed by a 5-year warranty, the DELTA Pro Additional Battery is ideal not only for emergency home backup but also for workshops, outdoor work, and events where reliable power is essential.

Note: This model is functionally equivalent to item 1ECO3602.
