Key Features

✅ Unmatched Energy Storage

71Ah capacity provides 30-50% more energy than standard industrial pouch cells, reducing the number of cells needed in large battery systems.

✅ Superior Power & Efficiency

1C continuous / 3C peak discharge supports high-power applications without excessive voltage drop.

✅ Long Lifespan & Reliability

2,000+ cycles at 80% depth of discharge (DOD) ensures 5-10 years of service in most applications.

✅ Space-Saving Pouch Design

Slim 12mm profile allows for high-density stacking in battery modules, optimizing pack volume.

✅ Scalable for Large Systems

Ideal for 48V to 800V battery configurations, making it perfect for EV buses, ESS, and grid storage.
