Description
The HOBBYWING XRotor Pro H300A 24S BLDC ESC is built for industrial and heavy-load drones, offering high voltage power density and reliable performance. With modular algorithm architecture, this drone ESC achieves up to 98% drive efficiency and 20% faster response.
The fully isolated throttle, communication, and power circuits ensure strong anti-interference for stable flight.
Equipped with dual-throttle redundancy, intelligent propeller control, and self-test protection, it guarantees safety and precision in demanding missions.
An advanced heat dissipation system—featuring top-bottom thermal conduction, 3D air-deflecting fins, and nano-coating—provides excellent IP55 protection (customizable to IP67).
Designed for VTOL and multi-rotor drones, the XRotor Pro H300A offers unmatched stability, durability, and efficiency under extreme environments.

Q1: How do I use and connect the ESC cable, and what are its definitions?
A1: For proper ESC cable connection and understanding each wire’s definition, always refer to the official technical documentation. Correct cable setup ensures safe operation and prevents ESC errors or motor issues.
Q2: How do I set the ESC ID?
A2: Setting the ESC ID is essential for synchronized multi-motor control. Follow the steps outlined in the technical documentation. Proper ESC ID configuration ensures accurate communication between the flight controller and all ESCs.
Q3: How do I update ESC firmware using DataLink?
A3: Firmware updates for Hobbywing ESCs using DataLink must follow the official guide. The documentation provides step-by-step instructions for safe ESC firmware updates to maintain motor performance and system stability.
Q4: What do the motor beep sounds and LED flashes mean?
A4: Motor beep patterns and ESC LED flashes indicate specific warnings or operational status. Always refer to the technical documentation for definitions. Understanding these signals helps with ESC troubleshooting and motor protection.
Q5: Can I use a different size or pitch propeller with FOC products?
A5: No. For FOC ESC systems, the motor, ESC, and propeller form a matched group. Only the recommended propeller with the corresponding firmware should be used. Using mismatched propellers can lead to motor overheating, ESC failure, or unstable drone flight.
✓ Keep Clean: Wipe the earphone surfaces with a soft, dry cloth regularly. Avoid using water or harsh chemicals.
