Built with high-quality components and coupled with cutting-edge firmware, the Seaking 60A V3.1 is featured by unmatched performance and reliability. Multiple safety adjustable options are in use, with the implementation of the low-voltage cut-off protection, thermal protection and throttle signal loss protection.
The Hobbywing patented heat-conductive copper bar cover on the power board of the Seaking 60A V3.1 can efficiently and effectively transfer heat to the integrated CNC machined billet aluminium water cooled heat sink housing thus keeping your ESC as cool as possible.
100% waterproof without the need of extra protection.
The built-in switch mode BEC with a maximum output of 6Amp and voltage of 6V make this ESC compatible with high voltage servo.
The special algorithm implemented in the ESC make the acceleration more incredible and sailing more stable.
The separate PRG/FAN port on the ESC can connect ESC to a program box (via the trio-color programming cable) and start ESC programming.

Installation & Connection

Connect the ESC, motor, receiver, battery and servo according to the wiring diagram below (Picture 1/2). Three wires from the ESC to the motor have no polarity, so you can connect them freely. Please recheck all the connections and ensure they are correctly connected before proceeding to step 2. (And you may find it’s necessary to swap two wires if the motor runs in reverse.)

For safety, please always keep the propeller away from human body or any other objects.

Red colour input wire is positive pole, Black colour input wire is negative pole.

Recommended for fresh water use only.
