It delivers a continuous 300A current (peak 1600A) and supports 5-14S LiPo batteries, ensuring massive power for large propellers. Featuring a built-in Bluetooth module, it allows seamless ESC programming, firmware updates, and real-time data logging via the HW LINK app. Its versatile BEC output powers high-torque servos, making it the ultimate choice for millennial pros who demand reliability, smart control, and raw power on the water. ## Description Product description Excellent waterproof performance (IP67). Users can use it directly without any waterproof treatment. Note: If water enters during use, please blow-dry each plug to prevent rusting. The integrated Bluetooth function (built into the switch) allows for ESC settings and upgrades via the mobile app, without requiring additional devices, making it simpler and more convenient. Data logging functionality enables viewing of various running data through the HW LINK app. Supports firmware upgrades for the ESC, allowing access to the latest features. Safety Warning • Ensure all devices in the system are connected correctly to prevent any damage to the system. • It is important to ensure that all wires&connectors soldered are properly secured. A good soldering station is recommended to do such a job to avoid short circuits, false soldering and overheating. • Do not attempt to drive two brushless motors with a single ESC, as this may cause damage to the ESC. • Please hold the boat in the air and ensure that the propeller do not touch human bodies or objects during setup, in order to avoid safety accidents. • The battery must be disconnected after use. There is a small draw even when the system is off, and will eventually fully drain the battery. This may cause damage to the ESC, and will NOT BE COVERED UNDER WARRANTY. Review: It’s a beast. Review: 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.
