Brushless Speed Controller ESC BEC for RC Airplane Quadcopter Helicopter

- Battery type: lithium battery / nickel hydrogen; - Overheat protection: built-in temperature detection circuit, MOS tube temperature is too high when the automatic turn off; - Overvoltage protection: the input voltage exceeds the input allowable range does not start, automatic protection, while issuing a rapid beep alarm sound; 4. comprehensive protection function: - Under voltage protection: set by the user through the program, when the battery voltage is lower than the protection threshold, the automatic reduction in output power;
