User Manual for Hobbywing Seaking V4 Brushless Electronic Speed Controller

Quick Start Guide

The Hobbywing Seaking V4 ESC requires calibration before its first use or when a new radio/receiver is installed. Ensure your transmitter throttle channel is set to default (100% EPA/DR) and the throttle trim is set to 0. Follow the ESC calibration process to define the throttle range (Full Throttle, Neutral, and Bottom positions) to ensure the motor operates correctly.

Safety and Warnings

• Ensure all wires and connectors are securely soldered and insulated.
• Do not attempt to drive two brushless motors with a single ESC.
• Always disconnect the battery after use to prevent deep discharge, which can damage the ESC.
• The system is IP67 waterproof; however, blow dry plugs after use to prevent rusting.
• Hold the boat in the air during setup to ensure the propeller can spin freely without causing injury.

Connections and Wiring

Motor Connection: There is no specific wire sequencing. If the motor rotates in the wrong direction, swap any two motor wires or adjust the "Motor Rotation" parameter.

Receiver Connection: Insert the throttle cable into the throttle channel of the receiver. The red wire provides BEC voltage; do not supply external power to the receiver unless the red wire is disconnected and insulated.

Battery Connection: Connect the ESC (+) to the battery (+) and (-) to (-). Reverse polarity will damage the ESC and void the warranty.

Water Cooling: Connect the water-cooling pipes to the ESC according to the boat's internal layout. Use clamps or ties to secure the tubes.

ESC Calibration Process

1. Turn on the transmitter and set throttle to neutral.
2. Pull the throttle trigger to full position and connect the battery.
3. Wait for the "Beep-Beep" tone (full throttle confirmed).
4. Release the trigger to neutral and wait for the "Beep" tone (neutral confirmed).
5. If using a board-type transmitter, follow the specific stick movements for full/half/bottom range as detailed in the manual.

Programming Methods

The ESC parameters can be adjusted using three methods:

• LED Program Card: Connect the throttle cable to the card, then connect the battery. Use the "ITEM" and "VALUE" buttons to adjust settings.
• LCD Program Box Pro/G2: Connect via the programming port and use the menu to select and save parameters.
• OTA Bluetooth Module: Connect the ESC to the module and use the HW Link App on your smartphone to adjust settings and view data logs.

LED Status Indicators

• Red light off: Zero throttle position.
• Red light on: Advancing.
• Red + Blue light on: Full throttle (100%).
• Flashing Red (Single): Low voltage protection.
• Flashing Blue (Single): Overheat protection (output reduced to 50%).
• Flashing Blue (Three): Current protection.
• Flashing Blue (Five): Capacitor overheat protection.

Troubleshooting

If the motor does not start, check the battery voltage and ensure the throttle signal is detected. If the motor rotates in the wrong direction, swap two motor wires or change the "Motor Rotation" setting. If the ESC enters protection mode (flashing lights), allow the unit to cool down or check the battery level.
