How to Use This Calculator
  1. Enter battery capacity (mAh), battery voltage, and hover current draw from your drone's specification.
  2. Set drone weight without payload and payload weight for the planned mission.
  3. Enter current wind speed to account for increased power in headwind conditions.
  4. Review estimated flight time (min), maximum no-load flight time, and total power consumption (W).
  5. Reserve at least 20–25% battery for emergency return — plan missions to land at 30% remaining.

What each input means

Battery Capacity
Battery capacity in milliamp-hours.
Battery Voltage
Nominal battery voltage (e.g., 6S LiPo = 22.2V).
Hover Current Draw
Current draw while hovering with no payload.
Drone Weight (no payload)
All-up weight of the drone without payload, including battery.
Payload Weight
Weight of camera, sensor, or cargo payload.
Wind Speed
Average wind speed during the flight.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Battery Capacity = 5200, Battery Voltage = 22.2, Hover Current Draw = 15, Drone Weight (no payload) = 2500 = 6 input(s) provided
  2. Calculate Estimated Flight Time
    Estimated Flight Time
    12.7 = 12.7
  3. Calculate Max Flight Time
    Max Flight Time
    16.6 = 16.6
  4. Calculate Adjusted Current Draw
    Adjusted Current Draw
    19.62 = 19.62
