hobby.rc-battery-flight Calculator
Estimates RC aircraft or drone flight time from battery capacity, discharge rate, motor count, and a buffer reserve percentage. Exceeding a LiPo battery's safe discharge depth permanently reduces capacity — this shows the time budget at safe usage.
Inputs
Capacity Mah
Maximum throughput or storage. Operating near 100% capacity typically increases failures and wait times.
Avg Current A
Rate of charge flow (A). I = V/R. Above ~100 mA through the body can be lethal. Fuses protect against overcurrent.
Efficiency
Useful output divided by total input, as a percentage. 100% is impossible due to losses (heat, friction, resistance).
Reserve Pct
Reference formula or conversion factor shown for context.
Results
flight time (min)
The computed duration or time value.
usable capacity (Ah)
Reference formula or conversion factor shown for context.
full capacity (Ah)
Reference formula or conversion factor shown for context.
reserve kept
Reference formula or conversion factor shown for context.
C-rating at avg draw
A standardised quality or risk rating on the applicable scale.
