It is a brushless DC motor speed controller. The low output resistance greatly improves the power balance, which in turn extends the battery life. EMAX BLHELI SERIES 30A ESC is programmed to run brushless dc motor. This ESC has a higher current handling capacity of 30A continuous and the peak current is 40A for the last 10 seconds only.

Based on BLHeli firmware, it is further optimized for excellent drive performance.

Low voltage protection, overheat protection and throttle signal loss protection.

Separate power supply for MCU and BEC, enhancing the ESC's ability to suppress magnetic interference.

The parameters of the ESC can be adjusted by the program card or the transmitter.

The gas range can be adjusted to match different receivers.

Equipped with internal linear BEC or BEC switch.

Max speed: 210,000rpm for 2 poles, 70,000rpm for 6 poles, 35,000rpm for 12 poles.
