How our specifications compare to the 2025/26 industry average.
| Metric | Industry average (2025/26) | YES-EU specs | Advantage for you |
| Cell capacity | 314 Ah | 530 Ah | Much higher density, smaller footprint |
| Cycle life | 6,000 – 8,000 | 12,000 | Nearly double the operational life |
| Longevity | 10–15-yr warranties, often ending at 60–70% SOH | 20 years @ 70% SOH | After 20 years, at least 70% of original capacity remains |
| First-year degradation | 5% – 7% | < 4% | More predictable performance |
Testing and certifications
