Dimensions | 220(L) × 188(W) × 190(H) mm | Excluding wiring harness. |
Cycle Life
Test Conditions | Cycle Count | Capacity Retention | Standard |
0.5C Charge + 0.5C Discharge | >1,000 cycles | ≥80% @100%DOD | IEC 61434-2015 (equivalent) |
Typical Discharge Profile:
- Voltage Platform: Stable between 25.6V and 20.4V at 0.5C discharge.
- High-Rate Discharge: Voltage drops faster at 50A (e.g., 20% drop within 10 minutes).
- Low-Temperature Performance: Minimal voltage sag at -20°C (-5% drop vs. 25°C).
