Last night my (brand new) ESC went up in smoke on the bench after functioning perferctly for 3 days. I gave it throttle, then brake and then poof. That said, is it possible for a

AI Customer Service$begingroup$ Not an answer, per se., since you didn''t ask this question -- 1C (or even 2C) is a much lower discharge capability than I''m used to seeing. I fly model

AI Customer Service2.Continuously output of battery's current need to be bigger than the ESC's. Working voltage of the motor is decided by the ESC, whilst the voltage of ESC is decided by the output of batteries. Hence the total voltage of batteries must be equal or less than the maximum voltage of motor.
An ESC can monitor current and have a current cutoff, but it delivers the same voltage for the same throttle imput regardless of the current flow that results. Also, the rated current of the motor, esc and battery do not necessarily reflect what you should actually run. The main factor is heat dissipation.
In practice you'd probably go for a 25A or 30A ESC to give yourself some margin, and you'll go for a battery that can deliver 20A at a nice conservative C rating like a 2000mAh pack rated at 20C but running at only 10C or a 2500mAh pack running at 8C. That way your components will be less stressed and will last longer
Working voltage of the motor is decided by the ESC, whilst the voltage of ESC is decided by the output of batteries. Hence the total voltage of batteries must be equal or less than the maximum voltage of motor. Maximum voltage of ESC should not be higher than what the motor can suffer. Current in ESC is larger than motor.
Some of the better ESC's do have current limiting, but experience in the flying field is that if you dork the thing into the dirt at full throttle, chances are that you'll damage the electronics due to overcurrent. An ESC could be designed to limit current in such a way (I've designed industrial motor controllers that do), but AFAIK ESC's don't.
Battery parameters: Voltage + capacity + discharge rate, for example: 3S (11.1V), 4200mAh,30C Motor parameters: Maximum current (A), maximum voltage (V), KV values. for example: LBP2860, Maximum Current is80A, Maximum Voltage is 17V and 3400MV. 1.Battery voltages should not be higher than the maximum voltage that ESC can suffer.
