Drone Flight Time Calculator

Estimate multirotor flight time from pack capacity and average current.

Battery & Load

Result

Estimated flight time
2.4min
at 0.80 usable capacity
Ideal flight time
3.0min

Estimate only — payload, flight mode, temperature, pack condition and conditions all change it.

Formula

  1. 1.Ideal (min) = Capacity (mAh) / (1000 × Average Current (A)) × 60
  2. 2.Estimated = Ideal × Usable Fraction

Worked example

  1. 1.Inputs: 1500 mAh, 30 A average, 0.8 usable.
  2. 2.Ideal = 3 min; estimated = 2.4 min.

Assumptions and limits

  • Aggressive flying can double the effective average.
  • This is an estimate — manage packs with timers and sag alarms.

FAQ

Why is my 5" quad only flying 3 min?

Freestyle draw is spiky — your average is closer to 25–35 A on a 1500 pack.

Assumptions

  • Same ideal-runtime formula as other battery tools.
  • Real FPV/freestyle draw varies hugely over a pack.
