Recommended Battery Capacity by Charging Current
Choose the right charging current for your battery capacity:
| Charging Current | Recommended Battery Capacity | Charging Time (Approx.) |
| 1.5A | 1.5Ah - 3Ah | 1.5 - 2.5 hours |
| 2A | 2Ah - 4Ah | 1.5 - 2.5 hours |
| 2.5A | 2.5Ah - 5Ah | 1.5 - 2.5 hours |
| 3A | 3Ah - 6Ah | 1.5 - 2.5 hours |
Note: For optimal battery life, we recommend charging at 0.5C to 1C rate. For example, a 5Ah battery should be charged at 2.5A-5A, but 2.5A-3A is safer for longevity.
