How It Works
Battery Energy (Wh) = Capacity (mAh) × Voltage (V) ÷ 1000. This is the total energy your battery stores.
Flight Time (min) = Battery Energy (Wh) ÷ Average Power Draw (W) × 60. We apply an 80% efficiency factor to account for real-world losses like voltage sag, wind resistance, and ESC heat.
Average Power Draw depends on your motors, propellers, all-up weight, and flight style. Hovering draws less than aggressive flying. Check your motor spec sheets for typical current draw at 50–75% throttle.
