ULS Independent Test Results
United Lithium Solutions completed independent testing of the Molicel M65A using dedicated battery testing equipment. These results show how usable capacity changes under different discharge loads.
| Discharge Test | Measured Capacity | ULS Notes |
|---|---|---|
| 1 Amp Draw | 6.8Ah | Low-load range test result |
| 10 Amp Draw | 6.0Ah | Medium-load performance test |
| 26 Amp Draw | 5.1Ah | Maximum rated continuous discharge test |
Under low-current testing, the sample delivered approximately 6.8Ah. As discharge current increased, delivered capacity decreased as expected due to voltage sag and internal resistance under higher load conditions. This is normal behavior for lithium-ion cells and is why ULS tests cells under multiple load conditions.
