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

Reliable water-cooled ESC designed for smaller RC boats

This ESC is aimed at hobbyists who demand consistent throttle control and dependable protection in tight installations. It works well in boats under 45cm and focuses on managing heat and preserving component life.

Comprehensive safety and stability

Quality internal components plus tested firmware yield smooth motor control while offering low-voltage cutoff, thermal shielding, and loss-of-signal safeguards to reduce the chance of failures on the water.

Heat transfer and water cooling explained

The design uses a heat-conductive copper bar to move heat into a precision CNC aluminium water-cooled heat sink, helping the ESC stay within safe temperature limits during longer runs.

Durable sealed housing

The sealed construction gives practical waterproofing straight from the factory so you can focus on setup and maintenance rather than extra potting.

Programmable BEC and accessory port

The built-in switch-mode BEC outputs 6V/6A for modern servos and the PRG/FAN port supports program box or fan attachments for easy tuning.

If you need a compact ESC that handles cooling and waterproofing without a lot of fuss, this unit offers a practical balance of protection and programmability for small boat projects.
