Overview
The Hobbywing SEAKING 200A HV V4 is a sensorless brushless ESC designed for RC boat applications up to Length <= 140cm. It features IP67 waterproof and dustproof protection for use without additional waterproofing treatment. If water enters during use, blow-dry each plug to help prevent rusting.
Key Features
- High-voltage support: up to 14S LiPo
- IP67 waterproof and dustproof design (protection may decrease with wear and aging; tested per GB/T 4208-2017 and IEC 60529 standards)
- Built-in Bluetooth for direct mobile app connection (HW LINK app) for parameter settings and firmware updates
- Built-in data logging: records 10 minutes of operation; view historical data (graph format) via the mobile app
- Bluetooth transmission effective up to about 5 meters
- Dual-channel water cooling system for enhanced heat dissipation
- Freewheeling function: reduces ESC temperature, improves deceleration when throttle is released, and enhances steering control during turns
- Capacitor overheating protection to help prevent damage caused by capacitor failure due to overloading
- Spark-resistant circuit to help protect battery plugs when using higher voltages (6-14S) and reduce strong electrical sparking
- AUX external control channel for real-time parameter adjustment by connecting the yellow signal wire to an unused receiver channel (function corresponds to AUX CH Function settings)

Troubleshooting
| Troubles | Possible Causes | Solution |
|---|---|---|
| The light does not turn on after power-up, the motor does not start. | 1. The battery voltage is not output to the ESC; 2. The switch is damaged. | 1. Check the battery, and whether the connection between battery and esc is good and whether the plug is soldered well; 2. Replace the switch. |
| The motor does not start after power-up, with a “beep-beep-, beep-beep-” warning tone accompanied by a flashing red light (approximately 0.5 seconds for each set of two-tone intervals). | The battery pack voltage is not within the range of support. | Check the battery voltage or change the battery for testing. |
| After power on, the red light flashes quickly. | 1. The throttle signal is not detected by the ESC; 2. The neutral point of the ESC is not calibrated correctly. | 1. Check if the throttle wire is plugged into the correct channel. Check if your transmitter is turned on. Check if the receiver ok. 2. Recalibrate the throttle travel. |
| The car is going in the reversed direction when the forward throttle is applied. | The transmission on the vehicle is different | Set the parameter item “Motor Rotation” to the opposite direction. |
| The motor suddenly stopped or significantly reduced the output in running. | 1. Possible interference; 2. The ESC enters into low-voltage protection state; 3. The ESC enters into overheat protection state. | 1. Check the cause of the interference in the receiver and check the battery level of the transmitter; 2. Replace the battery if red light keeps flashing; 3. The green light continues to flash for temperature protection, please continue to use after the ESC or motor temperature is reduced (it is recommended to reduce the load on the vehicle). |
| The motor stuttered, and unable to start. | 1. The motor is connected incorrectly; 2. ESC fault (partial power MOSFET burned out). | 1. Check the plugs and the solder points and whether the sequence of A, B and C wires is correct.; 2. Contact the dealer to handle the repair. |
| Going forward normally, but not reverse. | 1. The neutral point of the remote control throttle channel deviates from the brake area; 2. The parameter item “Running Mode” is set incorrectly; 3. The ESC is damaged. | 1. Recalibrate the esc,when the throttle trigger is at the neutral point, the esc lights are off; 2. Set the “Running Mode” to “Forward/Reverse with Brake”; 3. Contact the distributor to handle the repair. |
| The throttle travel setting could not be completed. | The ESC did not receive the correct throttle signal. | 1. Check whether the throttle cable is correctly connected to the receiver. 2. If the servo works normally,you can connect the throttle cable of esc to the steering channel to have a test, or change the transmitter/receiver system for test directly. |
