The XRotor Pro 300A is a 24S high-voltage grade square-wave brushless ESC developed by Hobbywing for heavy-lift industrial UAVs, belonging to the XRotor professional power series. It supports 18-24S LiPo battery packs with an operating voltage range of 54V~104.4V, delivering 120A continuous current and 300A peak current with abundant power reserve, capable of driving heavy multirotor platforms for heavy-load lifting, logistics transportation and other missions.
The product adopts a fully isolated circuit design to improve operational stability and anti-interference capability in high-voltage environments. It comes standard with serial communication for compatibility with mainstream industrial flight controllers. The throttle stroke is calibratable to adapt to different control habits and flight scenarios. A built-in DEO speed optimization switch allows switching between efficiency and power as needed. With IP55 dust and water resistance (IP67 customizable) and -20℃~50℃ operating temperature, it meets the reliability requirements of outdoor industrial operations.
