Hobbywing SeaKing PRO 120A Brushless boat controller

Innovative Turbo Function: The world's first marine ESC to implement the turbo sync function that will give the user an edge over the competition with instant turbo boost.
Splashproof: (IP55) The entire circuit board and all its components have undergone a nano-coating treatment; This makes the Seaking Pro 120A ESC splashproof.
Built-in HV BEC: The built-in BEC switching mode with a maximum power of 8 A and an adjustable voltage of 6 V / 7.4 V make the ESC compatible with various high voltage servos.
Durability and reliability: Reliable hardware (i.e. MOSFETs with very low internal resistance) combined with advanced software (low voltage cut-off protection, thermal protection, signal loss protection, etc.) ensures the durability and reliability of the ESC.) ensures the durability and reliability of the controller and the corresponding electronics.
Wireless programming/upgrading: With the Hobbywing WiFi module and iPhone or Android phone (with HOBBYWING WiFi Link software installed), the user can remotely program settings or update firmware without leaving the control station.
Efficient cooling system: Hobbywing's patented thermally conductive copper bar cover located on the controller's power board combined with the water cooling module efficiently and effectively transfers heat to the outside, keeping your controller cool.
