Uses average current—hover vs sport flying changes draw. Add a landing reserve in real flights; never over-discharge LiPos.
Time
hours = Ah ÷ I
Matches how many pilots sanity-check bench numbers.
Default
80% window
Tune to match your telemetry low-voltage cutoff.
2S–6S
Quick presets
Use your pack label if nominal differs.
Cruise vs punch
Mean current
Peak amps shorten time non-linearly if sustained.

Wh = Ah × V
Useful next to our watt-hour calculator.

We convert milliamp-hours to amp-hours, apply your usable percentage to model the charge you actually plan to spend in the air, then divide by average current. That yields time in hours; we display minutes for quick piloting decisions.
Ah_usable = (mAh ÷ 1000) × (usable% ÷ 100)Wh = Ah_usable × V_nominaltime_min = (Ah_usable ÷ I_avg) × 60Comparing energy? See our watt hour calculator.
