Review: Buy this - It’s a beast. Review: Absolute beast! - 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! ## Features - - IP67 fully waterproof design - With an IP67 protection rating, this ESC boasts outstanding waterproof and dustproof capabilities. It can be used immediately without any additional waterproofing treatment. - - Super Built-in BEC - The built-in BEC delivers up to 25A of current, with switchable output voltages of 6V, 7.4V, and 8.4V.
