Battery Weight to Hover Time.
Free drone calculators: flight time from battery and draw, distance per battery, charging planning, and mapping coverage math.
Payload to Hover Penalty
Adding a payload decreases flight time exponentially as motor RPM pushes into lower efficiency bands.
LiPo 20% Safe Reserve Rule
Never drain below 20% capacity (3.7V/cell) to prevent permanent voltage sag and chemical battery damage.
4K 60fps Bitrate Storage
Calculate gigabytes-per-minute at 100–150 Mbps to ensure micro-SD cards don't fill mid-mission.
DroneMath Calculators
Drone Flight Time Calculator
Real flight time from battery Wh and power draw — with wind, cold, and hover-vs-motion derates.
Drone Distance Calculator
Distance covered per battery at your flight speed — with the return-leg fuel accounting.
Drone Charging Log Calculator
The shoot-day charging schedule — batteries, charger wattage, and the rotation that keeps you flying.
