How to Calculate Drone Battery & Range
What is Drone Battery & Range?
The Drone Battery & Range Calculator estimates max safe flight time (with 30% reserve for return-home) and effective range factoring headwind reduction. Energy in Wh = capacity × voltage / 1000. Flight time = (0.8 × Wh) / Power × 60. Always reserve 30% for safe RTH.
Formula
Safe Time = (Wh × 0.8 / Power × 60) × 0.7; Range = Effective Speed × Time / 60
