About the SEAKING 300A HV V4 ESC
Unmatched Waterproofing & Cooling
Featuring an IP67 protection rating, the SEAKING 300A HV 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.
Advanced Power Management
The SEAKING 300A HV V4 is equipped with a powerful switch-mode BEC, capable of delivering up to 25A of current with selectable output voltages of 6V, 7.4V, and 8.4V. This ensures compatibility with high-torque and high-voltage servos for precise and responsive control. Additionally, the Freewheeling function enhances deceleration and steering control, while the AUX external control channel allows for real-time parameter adjustments using the remote, ensuring unparalleled control during competitive races.
