About the SeaKing 30A V4 ESC


Unmatched Waterproofing & Cooling

Featuring an IP67 protection rating, the SeaKing 30A V4 is designed to withstand water, dust, and splashes under normal usage conditions without requiring additional waterproofing treatments. Its dual-channel water cooling system enhances heat dissipation, ensuring the ESC maintains safe operating temperatures during intense use. For added protection, the ESC includes a spark-proof circuit and capacitor overheating safeguards, extending its durability in demanding environments.

Integrated Bluetooth & Data Logging

The built-in Bluetooth functionality simplifies ESC programming and firmware updates. Users can connect directly to the "HW LINK V2" app on their mobile devices to adjust settings, view historical data, and monitor performance in real-time without additional hardware. The ESC's internal logging module captures up to ten minutes of operational data, enabling post-run analysis through the app for optimal tuning and maintenance.

This ensures compatibility with high-torque and high-voltage servos for precise and responsive control.

*Tech Note: This ESC does not have reverse polarity protection. Ensure proper connections are made as outlined under step 5 per the owner's manual. Reversing polarity will damage the ESC.
