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 Classic (1024Wh) 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) [7]
25% less
self-heating [8]
Unrivaled Balance for Unmatched Battery Longevity
With 27% fewer cells per kWh, [9] 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.

Built to Last
From battery chemistry to structural design, DELTA 3 Classic (1024Wh) is engineered for extreme durability, environmental resilience, and whisper-quiet performance—delivering power you can count on for over 10 years.
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 Classic (1024Wh) is drop-resistant — protecting against overnight condensation and off-road bumps during transport. You get stable power even in the most demanding conditions.
Extreme Environment Resistance
DELTA 3 Classic (1024Wh) keeps your power flowing through freezing cold, scorching heat, humid environments (95% humidity tolerance), or coastal air (5% salt spray resistance)—for reliable energy anytime, anywhere. [10]
30dB Whisper-Quiet Operation Under Loads [11]
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 and solar generation—all with one intuitive dashboard. Set timed charging/discharging missions so that you can charge during off-peak hours and discharge during peak rate periods to save costs.
