DELTA Pro Ultra X Battery Pack

Next-Gen Battery Storage for the Ultra X System

The EcoFlow DELTA Pro Ultra X Battery Pack is the energy module purpose-built for the DELTA Pro Ultra X Inverter — EcoFlow's most advanced home energy system. Engineered with next-generation LFP cell architecture for higher energy density and improved thermal performance, it stores more energy in less space and handles higher charge/discharge rates than previous-generation battery packs. Stack multiple packs to build a scalable whole-home energy storage system from the ground up.

Higher Density. Better Performance.

The Ultra X battery architecture improves on the original DELTA Pro Ultra battery in energy density and sustained output performance. The result is a battery pack that can handle the faster charge rates and higher demand scenarios the Ultra X inverter is designed for — making it the ideal foundation for solar storage, high-demand home backup and time-of-use energy cost optimization.
