Seaking PRO 120A ESC 
The world's first marine ESC to have the turbo timing function, giving you the edge over the competition with instant turbo boost. Top-level competition programming guarantees the user first-class control and abundant programmable parameters for different competition environments. The built-in switch mode BEC features a maximum output of 8A and adjustable voltage of 6V/7.4V, making the ESC compatible with various high voltage servos. Reliable hardware (i.e. MOSFETs with extremely low internal resistance) combined with advanced software (features low-voltage cutoff protection, thermal protection, throttle signal loss protection, and etc) guarantees the durability and reliability of the ESC. The Hobbywing patented heat-conductive copper bar cover on the power board, combined with the water cooling module, efficiently and effectively transfers heat, keeping your ESC as cool as possible.
