HOBBYWING Seaking 30A V3 ESC - 30302060 Sealed Water-Cooled ESC  [HW-30302060]

Sealed and cooled ESC made for compact boat setups

Designed with practical on-water use in mind, this ESC delivers consistent throttle control and robust protection inside tight hulls. It is suited to smaller craft where efficient cooling and sealing are priorities.

Protection systems for worry-free running

The unit uses thoughtfully selected parts and firmware tuning to provide smooth control and built-in protections including low-voltage cutoff, thermal shutdown, and signal-loss response.

Copper heat path to CNC water sink

A heat-conductive copper bar transfers heat into a CNC-machined aluminium water-cooled sink so the ESC can sustain higher loads while keeping temperatures in check.

Factory waterproofing for active use

The sealed enclosure removes the need for additional potting for many users, letting you tackle rougher conditions with routine post-run care.

Stable BEC and simple tuning port

The internal switch-mode BEC supplies 6V/6A for modern servos and a separate PRG/FAN port allows quick programming with a program box or adding a cooling fan.

This ESC is a practical choice for pilots who need a compact, waterproof unit with proven cooling and programmable options for small to medium hobby boats.
