Expand Backup Power Capacity for Longer, More Reliable Energy Use

6kWh LiFePO₄ battery module designed for EcoFlow DELTA Pro Ultra X systems with scalable home backup and off-grid support

Scalable Energy Storage for Real Backup Needs

Each DELTA Pro Ultra X Battery provides 6,144Wh of additional storage, allowing your system to extend runtime based on actual demand. Whether powering essential circuits or supporting larger loads, adding batteries helps bridge longer outages without relying solely on the grid.

The system can scale significantly by stacking multiple batteries, supporting both short-term backup and long-duration energy independence depending on configuration.

Built for Safe, Long-Term Operation

The battery uses LiFePO₄ (LFP) cell chemistry, known for stability and long cycle life. It also includes a dual battery management system and multiple protection layers to monitor temperature, voltage, and current.

This design supports consistent performance over time with reduced risk of overheating or degradation, which is important for systems that operate regularly or remain on standby for emergencies.

Simple Integration with Existing Systems

The battery connects directly to the DELTA Pro Ultra X inverter using a plug-and-play design. No configuration is required beyond physical connection, allowing for quick expansion of an existing setup.

Once installed, the system can be monitored and controlled through the EcoFlow app, providing visibility into charge levels, usage, and overall system status.

Flexible Use Across Different Environments

This battery is designed for both residential and off-grid use. It supports applications such as:

• Home backup during outages
• Remote properties without stable grid access
• Solar energy storage systems
• Worksites requiring reliable power continuity

Its modular structure allows users to build a system that matches actual usage rather than overcommitting upfront.

 

What’s Included and System Components

Each battery module is supplied with the required components for integration:

• DELTA Pro Ultra X battery module
• Battery connection cable
• User documentation
