Drone Flight Time Estimate
Estimate how many minutes a drone can fly from its battery capacity, voltage and average current draw, with a safe landing reserve, free online.
À propos de cette calculatrice
Flight time = battery capacity (Ah) × usable fraction ÷ average current (A). Battery cells are 3.7 V (LiPo nominal), so a 4S pack is 14.8 V. Keep at least 20–25% in reserve for landing and wind. Heavier payloads and wind raise the current draw.
