Drone Battery & Flight Time Calculator
Flight Time Estimator
Estimate flight time based on battery and drone specs
Battery Comparison
Compare two batteries for the same drone
Formula
Flight Time (min) = (Battery mAh / 1000 × Voltage × Discharge%) / (Weight / Efficiency) × 60
Frequently Asked Questions
How is drone flight time calculated?
Flight time = Battery energy (Wh) / Power consumption (W). Energy = capacity (Ah) × voltage. Power consumption depends on drone weight and motor efficiency. Use only 80% of battery capacity to protect battery health.
What affects drone flight time?
Key factors: battery capacity, drone weight, wind conditions, flying style (hovering vs. aggressive), temperature (cold reduces capacity), altitude, and payload. Hovering is more efficient than constant maneuvering.
How do I improve flight time?
Use a larger battery (if thrust-to-weight ratio allows), reduce weight, fly in calm conditions, use efficient propellers, and avoid aggressive maneuvers. Keep batteries warm in cold weather.
