Description
EcoFlow DELTA Pro 3 Extra Battery
The EcoFlow DELTA Pro 3 Extra Battery is an expansion battery specifically designed to significantly increase the capacity of the DELTA Pro 3 power station. This module is intended for users who need long-term energy storage for home backup, off-grid use, or professional applications. The system works exclusively in combination with a compatible DELTA Pro 3 unit.
Performance & Functionality
The additional battery has a capacity of 4096Wh and immediately doubles the system’s total energy storage capacity when connected to the DELTA Pro 3. Multiple batteries can be added to expand the total capacity into a very large energy buffer for long-term use without grid power. LiFePO4 technology ensures a long service life of approximately 4,000 charge cycles to 80% capacity and stable performance under heavy loads. Connection is via a plug-and-play system with automatic recognition by the main unit.
Building Quality & Design
The battery is built with a sturdy and durable housing that is suitable for stacking and permanent installation. Its modular design allows for a neat and safe setup without the complexity of loose cables in the base configuration. The internal cells are designed for safety, stability, and consistent energy delivery, even during intensive use.
Why you need this
This extra battery is the easiest way to expand your DELTA Pro 3 system without having to purchase a second power station. It gives you greater autonomy during power outages and enables long-term off-grid use with a stable and scalable energy system.
