ECOFLOW DELTA 2 Max Smart Extra Battery 2048Wh expansion battery

Choose the DELTA 2 Max Battery to increase energy storage in a compatible portable power system. Its 2048Wh capacity provides extra reserve power for home backup, outdoor trips, and everyday use. When paired with a supported power station, it helps you run suitable devices for longer between charges.

Add More Backup Capacity

The DELTA 2 Max Battery expands the available storage of compatible power stations. A DELTA 2 Max can connect with up to two extra batteries, allowing the system to reach a total capacity of 6144Wh. More stored energy can be useful during outages or when access to a power source is limited.

Durable LFP Battery Chemistry

This expansion battery uses lithium iron phosphate technology. LFP batteries are designed for a long service life and stable everyday performance. The unit is rated for approximately 3000 cycles before retaining at least 80% of its original capacity under specified testing conditions. Actual results vary with usage, temperature, and care.

Simple Setup and App Control

The plug-and-play connection helps make expansion convenient. Use the supplied extra battery cable to connect the unit to a compatible power station, then follow the manual before switching the system on. With the EcoFlow app, you can monitor battery status and manage supported functions from a compatible device.

Useful for Home and Travel

Additional capacity can help support selected electronics, communication equipment, lights, and other devices connected through the power station. It is also useful for camping, road trips, and remote work. Runtime is not fixed, because each device uses energy at a different rate. Check the total load to estimate how long your system may last.

Space-Saving Construction

The battery measures about 464 × 235 × 283mm and weighs approximately 19kg. Its stackable design helps reduce clutter in a suitable setup. Place the unit on a stable surface, keep ventilation areas clear, and protect it from moisture during operation and storage.

Confirm Your Power Station Model

The DELTA 2 Max Battery works with selected models, including DELTA 2, DELTA Max 2000, and DELTA 2 Max. The DELTA 2 supports one extra battery, while compatible DELTA Max 2000 and DELTA 2 Max units support up to two. Verify the model and regional version before purchasing.

Please remember that this product stores extra energy but does not operate as a complete power station on its own. Use only approved accessories and follow the official instructions for connection, charging, and maintenance.
