Battery Discharge Graph

Battery discharge graph will be displayed here

⚠️ This is a simplified ideal discharge pattern for visualization. Actual voltage varies with C-rate, temperature, and battery age. This graph does not affect flight time calculations.

Assumptions

  • Hover-centric estimate (not forward flight optimized)
  • Assumes 80% usable battery capacity for safety
  • Uses average discharge voltage (3.5V/cell), not nominal 3.7V
  • Cruise time uses a multiplier on hover power (adjustable in Standard/Advanced)

When This Estimate Breaks Down

  • Actual flight time varies with wind, temperature, and flight style
  • High current draw causes voltage sag, reducing usable capacity
  • Forward flight efficiency depends heavily on airframe design
