How It Works

This calculator estimates drone flight time based on battery capacity, weight, and efficiency. The main factors affecting flight time are:

  • Battery Capacity: Higher capacity (mAh) generally means longer flight times, but also increases weight.
  • Drone Weight: Heavier drones require more power to stay airborne, reducing flight time.
  • System Efficiency: Motors, ESCs, and propellers all affect overall efficiency.
  • Flight Conditions: Wind, temperature, and altitude can significantly impact actual flight time.

Weight Based

Weight based calculation: Estimates power requirements based on drone weight: P=k×(weight^{1.5}), k: empirical coefficient, Then calculates current(P/V) and flight time(capacity×C-rate)
