SEAKING 120A V4

Introducing the SeaKing 120A V4  boat speed control from Hobbywing.

Ultra-high Reliability and Durability
Enables the ESC to deliver powerful performance while significantly reducing the risk of damage under high-load conditions.

Low voltage protection

Over-temperature protection

Throttle signal loss protection

Overload protection

IP67 Fully Waterproof Design
With an IP67 protection rating, this ESC boasts outstanding waterproof and dustproof capabilities. It can be used immediately without any additional waterproofing treatment.
Note:The IP67 rating ensures protection against splashes, water, and dust under normal use. It has been tested under controlled lab conditions according to GB/T 4208-2017 (domestic) and IEC 60529 (international) standards. However, the protection is not permanent and may decrease with wear and aging.

The built-in BEC features a high output current and adjustable output voltage with two or three levels, allowing it to effortlessly power a wide range of high-performance and high-voltage servos. This provides users with enhanced control and a more enjoyable experience.

Slim Design for Easy Installation
The new ESC is significantly narrower than the previous Seaking 30A/60A/120A V3 models, allowing for easier installation on narrow boats.

Built-in Data Logging for Performance Monitoring
By connecting the ESC to the OTA Bluetooth module, real-time data such as throttle position, voltage, temperature, and speed can be monitored via a mobile app. After operation, historical data can be viewed in the form of curve graphs, providing a clear overview of the ESC and motor’s performance and operating status.
Note:Due to the Bluetooth transmission distance, the effective distance is about 5m. Please refer to the instruction manual for the connection method!

Capacitor Overheating Protection
The capacitor overheating protection helps prevent damage to the ESC caused by capacitor failure due to overloading, safeguarding the unit against complete failure.
Note: The SeaKing 60A/30A V4 ESC don’t have capacitor overheat protection function.

Freewheeling Function
When enabled the Freewheeling function ESC temperature is COOLER

When the throttle is released the boat decelerates FASTER

Cornering control and handling BETTER

AUX External Control Channel for Real-time Parameter Adjustment
By connecting the yellow signal wire to an unused receiver channel, you can adjust ESC parameters (like reverse thrust) in real-time using the remote control, adding convenience to parameter management.

Supports ESC Firmware Updates
Supports firmware updates via Hobbywing USB LINK software and HW LINK mobile app, ensuring access to the latest features.
Note: Updating requires an LCD programming box or OTA module, sold separately.

Optimized Programmable Parameter
With 11 programmable parameters, the ESC is designed to meet competitive racing needs, offering a wider and more detailed range of settings.
