❓ What are C-ratings and why do they matter for drone batteries?

The C-rating indicates how quickly a battery can safely discharge its capacity:

A battery's continuous discharge rate is calculated by multiplying the capacity by the C-rating. For example, a 2000mAh (2Ah) battery with a 30C rating can continuously deliver: 2Ah × 30 = 60A

• Lower C-rating (20-30C): Suitable for camera drones and general flying
• Higher C-rating (75-100C): Required for racing drones and aggressive maneuvers

Choose batteries with C-ratings that match your flight style and motor requirements. Higher isn't always better - it often means higher cost and weight.
