Description
The EcoFlow DELTA Pro 3 Smart Extra Battery is designed to expand your home-energy storage system with ease. It works seamlessly with the EcoFlow DELTA Pro 3 portable power station, allowing you to scale from the base unit’s capacity up to 8 kWh (with one extra) or 12 kWh (with two extras) of total storage. The plug-and-play design makes setup straightforward: simply stack the extra battery module and use the flat link cable to connect with the main unit. The compact footprint and efficient LiFePO₄ (LFP) chemistry deliver both performance and durability, making this extra battery ideal for home-backup, off-grid use or extended runtime applications. On standby or in use, it integrates internally so that the system treats it as a unified storage bank, avoiding complexities. With a long product life (4000 cycles to 80% capacity) and industrial-grade construction, it’s built for real-world energy resilience.
