FPV Flight Time Calculator
Enter your pack capacity and average current. Freestyle and racing draw far more than cruising, so use your OSD or blackbox average if you have it.
Result
- Estimated flight time
- 3.1 min
- Pack voltage (nominal)
- 22.2 V
- Pack energy
- 28.9 Wh
Land around 3.5 V per cell under load and store packs at about 3.8 V per cell. Cold batteries give noticeably shorter flights.
How this calculator works
Flight time in minutes = capacity in Ah x 0.8 usable / average amps x 60. Pack energy in watt-hours = capacity in Ah x cells x 3.7 V nominal, which matters for airline carry-on limits.
