The Hobbywing Seaking 120A is a water-cooled brushless electronic speed controller (ESC) designed for RC ships and boats. It supports operating voltages from 7.4 V to 22.2 V (2S–6S LiPo) and delivers a continuous current of 120 A.
Water-cooled design for reliable cooling even under full load
Integrated 5A BEC supplies receiver and servos with stable 6 V
Compatible with brushless motors for maximum efficiency and power
Suitable for 2S to 6S LiPo batteries – flexible use in various boat models
Robust construction and 24-month manufacturer warranty for long-term investment security
What sets the Seaking 120A apart
The Seaking 120A impresses with its water-cooled housing that maintains optimal temperatures even under high current. Thanks to the integrated 5A BEC, no external receiver battery is needed, saving weight and space. The precise throttle response and programmable settings (e.g., brake, timing) make it the first choice for ambitious RC boaters.
Ideal for...
This model is perfect for RC boats such as speedboats, motor yachts, or workboats in 1:10 to 1:8 scale. Both beginners with their first self-build projects and experienced modelers benefit from the robust construction and high current capacity.
How to use the Seaking 120A
Connect the ESC to the motor, receiver, and battery according to the manual. Pay attention to correct polarity and use suitable connectors for 120 A. After connection, the ESC can be adapted to your driving environment via programmable parameters. A dry test is recommended before the first run.
