RedHobby 50A Bidirectional BEC Brushless ESC with 5V/3A Output for 2-4S LiPo RC Cars, Boats, and Underwater Thrusters
The RedHobby 50A Bidirectional BEC ESC is a high-performance brushless electronic speed controller built for RC cars, boats, and underwater thrusters running on 2-4S LiPo batteries. Engineered with genuine, high-quality components, this speed controller delivers a continuous 50A current with a 60A burst rating, ensuring reliable power handling across demanding RC applications. The integrated 5V/3A line BEC provides a stable power output for connected receivers and servos, making it a dependable all-in-one solution for competitive and recreational builds alike.
Weighing just 40g, the compact and lightweight form factor allows for easy installation in space-constrained RC platforms. The ESC supports 1:1 bidirectional power output, enabling smooth and responsive forward and reverse movement without power loss in either direction. With BLheli-S firmware at its core, the controller offers finely tunable throttle response and is compatible with a wide range of receivers. The default bidirectional mode, combined with multiple onboard protection systems, makes this ESC well-suited for both first-time builders and experienced RC enthusiasts looking for a robust, plug-and-play speed control solution.
Key Features
- Continuous and Burst Current Rating: 50A continuous current and 60A burst current, capable of handling high-load RC applications without throttling performance.
- Bidirectional Mode Support: Factory-default bidirectional mode provides full 1:1 power in both forward and reverse directions; direction selection is programmable via parameter settings.
- Integrated 5V/3A Line BEC: On-board battery elimination circuit outputs a stable 5V at 3A, sufficient to power receivers, servos, and other accessories directly.
- 2-4S LiPo Compatibility: Supports a 2-4S LiPo voltage range (7.4V-16.8V), accommodating a broad selection of RC battery configurations.
- BLheli-S Firmware Platform: Built on the BLheli-S platform for advanced motor timing control, smooth throttle linearity, and compatibility with ESC configuration tools.
- Multiple Protection Functions: Features low-voltage cut-off protection, over-temperature protection, and signal-loss protection to safeguard both the ESC and connected components during operation.
- Throttle Stroke Calibration: Adjustable throttle stroke range ensures compatibility with different RC receivers and provides a smooth, precise speed-control feel tailored to the user's preference.
- Lost Equipment Warning Function: If the throttle remains at the lowest position for a set period, the ESC emits an audible beep to assist in locating misplaced or crashed RC equipment.
- Compact and Lightweight Build: At 40g with a space-efficient form factor, the ESC integrates easily into RC cars, boats, and underwater ROV frames without adding unnecessary weight.
- Plug-and-Play Operation: Generally requires no throttle calibration out of the box; neutral throttle position at start-up initiates operation, reducing setup time significantly.
