    Expandable capacity

    Increase the capacity of DELTA 2 Max with an extra 2048Wh.

    Triple the power

    2-6kWh expandable capacity to fit your energy storage needs. Add up to two DELTA 2 Max Smart Extra Batteries to gain a capacity of 6144Wh, ideal for home backup, RVing, outdoor adventures, and everyday use. Much more affordable, it costs up to 30% less than a power station of the same capacity.

    10-Year Long-lasting LFP Battery

    Durable, Safe, Lightweight

    With its upgraded LFP battery chemistry, the DELTA 2 Max Smart Extra Battery has a lifespan of 3000 complete cycles until it reduces to 80% capacity. You'll get pretty much 10 years of power, even if you use it every day. That's 6× longer than other power stations with a similar capacity and output.

    Easy to use

    There's no setup. Just plug it into your power station for more energy storage. Using the EcoFlow app, you can charge and monitor the DELTA 2 Max Smart Extra Battery with ease.

    Stackable, space-saving design

    Featuring an ergonomic, compact design, the DELTA 2 Max Smart Extra Batteries can be securely stacked on top of power stations and each other to save space and minimize clutter.
