C-rating indicates a battery’s maximum continuous discharge rate. The formula is: Maximum Current = Capacity (in Ah) × C-rating.
For example, a 2000mAh (2Ah) battery with a 30C rating can deliver: 2 × 30 = 60 amps continuously.
Typical C-ratings for different drone types:
- Photography drones: 15-30C
- Racing drones: 75-150C
- Professional cinematography: 25-45C
Higher C-ratings allow for more powerful acceleration and better performance under load, but may reduce battery life. Choose based on your drone’s power requirements and intended use.
