About the SeaKing 120A V4 ESC


Unmatched Waterproofing & Cooling

Featuring an IP67 protection rating, the SeaKing 120A 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. 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.

*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.

Leaves an EXTREMELY SHARP edge - cuts off entire lid from sides of can!
Color: Blue, Color: Blue
This can opener cut off the whole top of the tuna cans and left an insanely sharp, wobbly, very thin edge of the top of the can that nearly cut me because there was no heavy metal lip left behind to hold the structure of the top of the can! This is a very bad feature that is going to really hurt someone! I do NOT recommend this for anyone! Needs a product recall!

Lackluster
Color: Black, Color: Black
It does what it’s supposed to but only for a couple of cans before it dies. I’ve learned that I have to charge it before I put it away or it’s dead when I need it next and that’s after 2-3 cans. It’s small and fits in my drawer nice, does what it’s supposed to, just a little disappointed in how long it lasts

Better way to open a can
Color: Blue
I may not have arthritis, but it saves time and energy. I will be buying another one for the band concession stand. It beats using an original can opener.
