These protection strategies are specifically
Designed for boat applilcations.

Enables the ESC to deliver powerful

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.
Splash protect

dustproof
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.

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.
