Key Features

• 14S High Voltage Support with 200A Continuous Current — This ESC supports input voltage from 5S to 14S LiPo batteries with a peak current rating of 1000A and continuous output of 200A, delivering the raw power needed for high-performance RC boats. This exceptional current capacity means you can run multiple high-performance motors or extremely demanding applications without worrying about current limitations or performance throttling.
• IP67 Fully Waterproof Design — With an IP67 protection rating, this ESC boasts outstanding waterproof and dustproof capabilities that have been tested under controlled laboratory conditions according to both GB/T 4208-2017 domestic standards and IEC 60529 international standards. The waterproof design means you can use the SeaKing 200A HV V4 immediately without any additional waterproofing treatment, making it perfect for demanding aquatic environments. Note that the protection is not permanent and may decrease with wear and ageing, so regular maintenance is recommended for long-term reliability.
• Built-in Bluetooth with Mobile App Control — The ESC features a built-in Bluetooth module allowing easy connection to Hobbywing's HW LINK mobile app for comprehensive parameter settings, real-time data reading, and firmware upgrades without requiring any additional programming devices. This user-friendly wireless connectivity (effective up to approximately 5 metres) makes tuning and configuration straightforward, whether you're at the water's edge or in the workshop preparing your RC boat for competition.
• Built-in Data Logging for Performance Monitoring — Equipped with an internal logging module, this ESC can record up to 10 minutes of operational data including performance metrics for both the ESC and motor. By connecting to the mobile app after your session, you can view historical data in graph format, allowing detailed analysis of both ESC and motor performance to optimise your setup for maximum efficiency and speed.
• Powerful 25A Built-in BEC with Switchable Voltage Output — The integrated Battery Elimination Circuit (BEC) delivers up to 25A of current with switchable output voltages of 6V, 7.4V, or 8.4V, providing seamless power for high-torque and high-voltage servo systems. This eliminates the need for a separate receiver battery pack in many applications, simplifying your RC boat setup and reducing weight and complexity.
• Built-in Spark-proof Design for Safety and Protection — The ESC includes a spark-proof circuit that protects battery plugs from damage when using higher voltages (6S to 14S), whilst also preventing injuries from strong electrical sparks that can occur during connection and disconnection. This safety feature is particularly valuable when working with high-voltage battery packs, protecting both your equipment and yourself.
• Dual-Channel Water Cooling System — This ESC features a sophisticated dual-channel water cooling system providing enhanced heat dissipation and ensuring the ESC remains within a safe operating temperature range during extended use. The water cooling technology is critical for maintaining consistent performance during competitive racing or prolonged sessions, preventing thermal throttling that could compromise your boat's speed and control.
• Capacitor Overheating Protection — The capacitor overheating protection circuit helps prevent damage to the ESC caused by capacitor failure due to overloading, safeguarding the entire unit against catastrophic failure and extending the lifespan of your expensive electronics.
• Freewheeling Function for Improved Control and Cooling — The freewheeling function reduces ESC temperature whilst improving deceleration when the throttle is released and enhancing steering control during turns. When enabled, the boat decelerates faster when you release throttle; when disabled, deceleration is more gradual, allowing you to fine-tune the handling characteristics to match your driving style and preferences.
• 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 your remote control transmitter. This on-the-fly tuning capability is invaluable during competitive racing, allowing you to make critical adjustments without stopping your boat to reprogram settings.
• Versatile 11 Programmable Parameters — The SeaKing 200A HV V4 offers 11 programmable parameters designed to meet competitive racing needs, providing a wider and more detailed range of settings than many competing ESCs. This flexibility ensures you can optimise every aspect of the ESC's behaviour to match your specific boat configuration, motor choice, and driving preferences.
• Sensorless Brushless Operation — This ESC is designed to work with sensorless brushless motors, offering the smooth, efficient power delivery and minimal maintenance that modern brushless technology provides, without the complexity and cost of sensored systems.
