Bidirectional Water-Cooled 40A Electronic Speed Controller for RC Ships, Underwater Thrusters, and Marine Propulsion Systems - 2-6S LiPo Compatible with Integrated 5V 3A UBEC
This bidirectional water-cooled 40A electronic speed controller is designed for stable and efficient motor control in marine and underwater remote-control applications. Supporting 2-6S LiPo battery input, it delivers reliable 40A continuous current output along with a regulated 5V 3A UBEC for powering receivers and onboard electronics. The water-cooling system - fed through a 4.8 mm fin interface — ensures effective heat dissipation during prolonged operation, making it well-suited for RC ships, pneumatic propulsion systems, and underwater thrusters.
Built for responsive and precise handling, this ESC offers smooth bidirectional control with direct-reverse functionality, enabling quick forward and reverse switching without any braking delay. Its plug-and-play operation eliminates throttle stroke calibration, allowing fast setup and easy integration into existing marine builds. With durable construction and consistent power delivery, it performs reliably in demanding underwater and marine environments where continuous operation and quick throttle response are critical.
