Performance & Reliability 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 cutoff protection, thermal protection and throttle signal loss protection. Efficient Cooling System 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 aluminum water cooled heat sink housing thus keeping your ESC as cool as possible. Waterproof Design 100% waterproof without the need of extra protection. Built-in BEC The built-in switch mode BEC with a maximum output of 6Amp and voltage of 6V make this ESC compatible with high voltage servo. Special Algorithm Design The special algorithm implemented in the ESC make the acceleration more incredible and sailing more stable. Separate PRG/FAN Port 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.
