Built with high-quality components and cutting-edge firmware, the SeaKing 180A V3.1 delivers unmatched performance and reliability for RC boats. The Hobbywing patented heat-conductive copper bar cover on the power board efficiently transfers heat to the integrated CNC machined billet aluminium water-cooled heat-sink housing to keep the ESC cool. The unit is 100% waterproof (IP67) without the need for extra protection, and brand-new software has been specially designed for RC boats. The built-in switch-mode BEC with a maximum output of 6A at 6V makes this ESC compatible with high-voltage servos. A separate PRG/FAN port allows connection to a program box via the trio-colour programming cable for easy ESC programming.

Brushless electric motors and ESCs have large amounts of torque at any given RPM. Using too-tall gearing, or a vehicle that is too large or heavy, can result in damage and/or product failure. Please consult your manual and select gearing suitable for the vehicle and terrain. Damage caused by overloading or abuse is unlikely to be covered by the manufacturer's warranty. Always monitor your ESC and motor temperatures closely after modifying your system to ensure they stay within the safe operating limits.
