ESC Recommendation
Each ESC should be rated for at least
2A(per motor)
💡 Total current is from battery pack. Per-motor current is for ESC sizing.

C-rate (1.0C) is within safe limits.

Check Motor Specs

Assumptions

  • Current = Power ÷ Voltage (Ohm's law)
  • Peak current estimated as 1.4× average (typical burst)
  • C-rate warnings at 8C (caution) and 12C (high risk)

When This Estimate Breaks Down

  • High C-rates cause voltage sag and heat buildup
  • Aggressive maneuvers may exceed peak estimates
  • Battery age and temperature affect actual performance
