EcoFlow DELTA Pro additional battery

The EcoFlow DELTA Pro Additional Battery expands the capacity of your DELTA Pro power station up to 10.8 kWh, providing long-lasting, reliable energy for home backup, professional work, and off-grid use.

The EcoFlow DELTA Pro Additional Battery is designed to significantly extend the runtime of the EcoFlow DELTA Pro power station. By connecting one additional battery, you double the system capacity from 3.6 kWh to 7.2 kWh. Adding a second unit increases the total capacity to an impressive 10.8 kWh, making it a powerful solution for extended outages, demanding workloads, or long-term off-grid applications.

Once connected, the DELTA Pro and additional batteries charge and discharge simultaneously and evenly, ensuring optimal performance and battery health. You can take advantage of EcoFlow’s MultiCharge technology, allowing charging via AC outlets, solar panels, or EV charging stations—anytime and anywhere.

The additional battery features a front-facing LCD display that provides clear, real-time information such as remaining capacity, input/output status, and time to full charge. For added convenience, the battery can also be monitored and controlled remotely through the EcoFlow mobile app, keeping you informed even when you’re away.

Built with durable LFP (LiFePO₄) cells, the DELTA Pro Additional Battery offers exceptional longevity and safety. Its versatility makes it suitable not only for emergency home backup, but also for workshops, outdoor work, events, and everyday power needs.
