DELTA Pro Ultra Battery Pack

6kWh Per Pack. Scale to 30kWh.

The EcoFlow DELTA Pro Ultra Battery Pack is the energy reservoir at the heart of EcoFlow's most powerful home energy system. Each 6144Wh LFP module pairs with the DELTA Pro Ultra Inverter to build a complete home energy storage system — starting at 6kWh for a single pack and scaling up to 30kWh by adding up to four additional packs. This is not a portable power station. This is a residential energy storage module designed for serious, long-term home backup.

LFP Chemistry — Built for Decades

LiFePO4 (Lithium Iron Phosphate) chemistry is the safest, longest-lived lithium battery technology available. Rated for 3,500+ charge cycles to 80% capacity — at one full cycle per day, that's nearly 10 years before meaningful degradation. It cannot combust or vent toxic gases even under physical damage. It's the same chemistry trusted in electric city buses, grid storage systems, and industrial UPS installations worldwide.

Modular — Grow When You're Ready

Start with one battery pack for 6144Wh of home storage and add packs over time as your energy needs or budget grows. Each pack connects directly to the DELTA Pro Ultra Inverter through a dedicated battery connection cable. The system manages charge distribution across all connected packs automatically. Weatherproof casing supports indoor or sheltered outdoor installation.
