Attributes of Esc 30A Simonk Specification; Max cont.current: 30A Peak current: 40A (10s) Voltage: 2-3S lixx BEC: 5V/3Aweight=31g Description: efficiency of this simonk is 100% N-FET design. Highest accuracy with Crystal Oscillator (Temperature won’t affect the PWM operating range like other cheap ESC’s). No low voltage cutoff, because any cutoff in a multirotor = crash….
