The Hobbywing XRotor Pro H300A 24S G3 is a high-voltage BLDC ESC designed for heavy-lift industrial UAV propulsion systems. Built for large multirotor drones, VTOL lift motors, and cruise propulsion applications, it provides strong current handling, reliable control, and efficient power delivery.
With high power density, CAN communication, optional RS485 support, and advanced protection features, the XRotor Pro H300A 24S G3 is engineered for demanding UAV platforms requiring stable performance and long-term reliability.
High-Voltage Heavy-Lift Performance
The XRotor Pro H300A 24S G3 supports 12–24S LiPo battery systems.
With 150 A continuous current and up to 300 A peak current for 3 seconds, it is designed for high-power industrial UAV propulsion systems.
Its high-voltage architecture helps reduce current load, improve efficiency, and support stable operation under demanding flight conditions.
BLDC Drive Technology
The ESC uses BLDC drive technology for strong motor compatibility and stable operation.
Hobbywing’s modular architecture algorithm improves drive efficiency and response speed, providing smoother throttle control and reliable motor performance.
This makes the ESC suitable for heavy-load multirotor motors, VTOL rotor motors, and cruise motors.
Reliable Communication & Control
The XRotor Pro H300A 24S G3 supports CAN communication, with RS485 available as an optional customized communication interface.
Dual-throttle redundancy improves control reliability and provides safer integration for professional UAV systems.
Throttle and communication isolation help improve anti-interference performance in demanding operating environments.
Black Box & Fault Storage
The ESC features black box logging for propulsion data and fault recording.
This allows easier fault analysis, maintenance tracking, and post-flight diagnostics.
The logging system helps improve operational reliability for professional UAV fleets.
Rugged Protection & Heat Dissipation
The XRotor Pro H300A 24S G3 features IP55 protection for dust and water resistance.
Its optimized heat dissipation structure helps maintain stable operating temperatures during high-load operation.
The compact and lightweight G3 design improves power density while reducing overall system weight compared to previous generations.
