Long-Lasting, Durable, Always Ready for Emergencies
Automotive-grade full-tab LFP cells
Rugged exterior and intelligent BMS for unmatched reliability
Automotive-grade Full-Tab LFP Cells: Next-Level Battery Reliability
DELTA 3 Ultra Series is equipped with automotive-grade full-tab LFP cells. The full-tab design reduces resistance, enhances efficiency and safety, and provides higher capacity with less heat, resulting in a long battery lifespan.
25% more
efficient power flow (thanks to lower resistance: 1.5 mΩ vs. 2 mΩ) [14]
25% less
self-heating [15]
Unrivaled Balance for Unmatched Battery Longevity
With 27% fewer cells per kWh, [16] our 16-cell design runs cooler, lasts longer, and delivers greater stability. Each cell is rigorously tested for capacity, voltage, and internal resistance—resulting in a highly uniform pack that protects against overcharging, imbalance, and premature wear.
16-cell uniform set per 1 kWh
Rigorously tested for capacity, voltage, and internal resistance
Built to Last
From battery chemistry to structural design, DELTA 3 Ultra Series is engineered for extreme durability, environmental resilience, and whisper-quiet performance—delivering power you can count on for over 10 years. [2]
Smart, 24/7 Battery Protection
EcoFlow’s advanced BMS uses a high-performance ARM Cortex chipset and intelligent algorithms to monitor your battery in real time. By tracking SOC, SOH, temperature, and more, it ensures peak performance, extended battery life, and worry-free operation.
EV-Grade CTC Structure
Built with a cell-to-chassis (CTC) structure, DELTA 3 Ultra Series is drop-resistant (0.2m) —protecting against overnight condensation and off-road bumps during transport. You get stable power even in the most demanding conditions. [20]
Extreme Environment Resistance
DELTA 3 Ultra Series keeps your power flowing through freezing cold, scorching heat, humid environments (95% humidity tolerance), or coastal air (5% salt spray resistance). [17]
Class B EMC Certification
Certified to Class B EMC standards, it won’t interfere with TVs, Wi-Fi, or other home electronics.
25dB Whisper-Quiet Operation Under Loads [18]
Powered by X-Quiet™ 3.0, EcoFlow’s stepless fan control adjusts airflow smoothly to maintain precise thermal regulation—keeping your home or workspace peacefully quiet, even under heavy loads.
Deeper Insights, Easier Control
Monitor your energy usage, savings, and solar generation—all with one intuitive dashboard. Easily track battery status, real-time electricity rates, and financial savings.

Scheduled Tasks [19]
Cut Costs, Not Comfort
DELTA 3 Ultra Series intelligently optimizes energy usage to help lower your electricity bills while powering your home sustainably. Set automated tasks to charge during off-peak evening hours and discharge during the day.
Intelligent Mode
Charge During Off-Peak, Use During Peak
Intelligent Mode lets you set custom charging and discharging schedules based on your local electricity rates. Charge when energy is cheapest, and discharge during peak hours to cut costs without lifting a finger. [19]
Self-Powered
Reduce Grid Dependency, Lower Electricity Costs
Self-Powered mode stores solar energy and powers your home once battery levels exceed a preset reserve. It minimizes grid use while maximizing solar efficiency—ideal for managing fluctuating energy prices and enhancing your energy independence.
To use this feature, update the software to V6.14.5 or above and upgrade the firmware to V7.80.99.52 or above.
