Hobbywing Seaking Pro 120A Brushless ESC with Water Cooling

The Hobbywing Seaking Pro 120A is designed specifically for racing boats especially the ECO / MONO1 / other competition boats (<=1000mm). The Pro 120A is lightweight for marine competition which helps with speed and endurance. It comes with first-class control and has abundant programmable parameters.

The whole circuit board is covered in a nano-coating treatment to make the ESC splash proof (IP55). To make the ESC compatible with high voltage servos there is a built-in switch mode BEC with a maximum of 8A output and adjustable voltage of 6V/7.4V. Reliable MOSFETs with extremely low internal resistance combined with advanced software (featuring low-voltage cutoff protection, thermal protection, throttle signal loss protection, etc) guarantees the durability and reliability of the ESC and relevant electronic devices.

To give that extra edge over the competition the PRO 120A is the world’s first marine ESC with a turbo timing function for instant turbo boost. To keep things cool there is a patented Hobbywing heat-conductive copper bar cover on the power board to combine with the water cooling module to whisk away the heat as quickly as possible.

Programming or software updating can be a breeze utilizing the Hobbywing WiFi module (sold separately) and a smart phone (with Hobbywing WiFI Link APP). Update the ESC parameters or upgrade firmware remotely with ease. Otherwise, use the LCD Program Box (sold separately) to change parameters.
