HOBBYWING SEAKING 300A HV V4 ESC (5-14S)

This thing is an absolute beast, purpose-built for handling those massive propellers that would melt lesser speed controllers. It delivers smooth, consistent, and brutal power. Do NOT skimp on your batteries. The 300A current draw means you absolutely must pair this ESC with top-quality LiPo packs that have a genuinely high C-rating (discharge capability). If you use mediocre or aged batteries, the SEAKING will draw so much current that it will rapidly stress and cook the battery, leading to puffing, failure, and potential safety issues. Bottom line: If you're ready for high voltage and huge props, this ESC delivers, but ensure your power source is just as capable!

It’s a cool esc meaning it stays cool 11000 mah packs only last 6 minutes btw but it will stay cool no voltage cuts the whole time.
