HOBBYWING launches the brand-new electronic speed controller - XRotor Pro H300A 24S FOC V2, which is perfectly compatible with UAV motors for heavy-load multirotors, VTOL rotor, and cruise applications.

Featuring high voltage, high power, and high current withstand capacity, this drone ESC meets heavy-load demands of multirotor and VTOL UAVs.

High Voltage, High Power, and Driven by FOC

XRotor Pro H300A 24S V2 drone Speed Controller supports up to 28S LiPo battery, featuring 100V voltage and continuous current of 140A (depending on the used drone motor and propeller).

Efficient and Precise Drive Control Technology

This H300A FOC V2 UAV ESC utilizes HOBBYWING’s mature and reliable Field Oriented Control (FOC) drive algorithm, i.e., vector control.High efficiency and low noise, achieving precise control and energy recovery.

Hobbywing XRotor Pro H300A 24S V2 drone ESC adopts fully isolated design of throttle, communication, and power circuits optimizes response speed, throttle linearity, temperature rise, and anti-interference capabilities in an all-round manner, significantly enhancing operation stability of the UAV propulsion system and extending the drone’s flight time.

Exceptional Heat Dissipation, Strong Protection

The top and bottom shells of this 300A drone Speed Controller are made of high thermal conductivity materials, attached to the internal heat-generating areas, ensuring direct contact with the heat sources and achieving efficient heat conduction.

The 3D air-deflecting fin crisscross in HOBBYWING H300A 24S V2 ESC pattern expands the heat dissipation area while accelerating the export of internal heat through propeller airflow, ensuring stable operation of the drone electronic speed controller even under high-temperature conditions.

The new-released H300A drone ESC employs outlet hole with sealing rubber ring design. Combined with PCB treated with the nano-coating process, it forms a dual protection, achieving an IP55 ingress protection rating (customizable up to IP67).

Redundancy Control, Intelligent Safety Protection

XRotor Pro H300A 24S FOC UAV ESC supports CAN Digital Control (RS485 reserved for customization) and PWM Analog Control, ensuring fast and seamless switching of throttle signals under abnormal conditions, enhancing signal stability and boosting drone operational safety.

The self test function on power up allows this drone Speed Controller to identify faults before takeoff. Multiple protection mechanisms including intelligent protection, reporting warnings, and quick restart mechanisms, help reduce the losses of sudden failures and provide comprehensive protection for flight safety.

Open Software Ecosystem, Intelligent Interconnection

With HOBBYWING’s proprietary host computer software (DataLink), drone operators can easily adjust drive parameters and CW/CCW rotations of the motor. This UAV ESC from Hobbywing - XRotor Pro H300A 24S FOC V2 ESC also supports firmware OTA upgrade and built-in blackbox, providing millisecond-level recording of real-time operational data, enabling comprehensive traceability analysis and fault diagnosis of drone flight.

Strict Testing Validation, Long-Term Reliability

H300A 24S FOC V2 drone ESC undergoes stringent environmental testing,including drive compatibility, temperature/humidity combined vibration tests, and high & low temperature operation tests. These tests ensure outstanding durability and stability of the UAV ESC even in complex and extreme environments.
