Electronic Speed Controller
To elevate your riding experience and ensure absolute safety, our electronic controller is equipped with multiple protective features: High-Temperature Protection slows the speed when safe temperature limits are reached, safeguarding the equipment. Over-Current Protection maintains the safety of both battery and motor. Motor Stall Protection activates when excessive load or obstacles cause the propeller to stall, preventing potential damage or safety issues. Signal Loss Protection steps in to ensure your safety if the remote control signal is lost. Return Trip Protection guarantees you have enough power to return safely when the battery is running low.
Remote Control
Ergonomically crafted with intuitive design, our remote control features a robust safety waterproof case, proudly achieving an IP68 rating. Safety takes precedence, outfitting our remotes with dual safety mechanisms: a safety switch and an automatic disconnect function. The signal will sever immediately if submerged or upon release of the safety switch, securing safety throughout. Control your speed effortlessly with a dial for gradual acceleration, outperforming traditional remotes in efficiency, allowing you to steer confidently like a seasoned captain. Quick and user-friendly connectivity empowers you from the first ride. Should your surfboard's battery run low during deep-sea adventure, the remote will vibrate five times every 30 seconds, urging a swift return to shallower waters to avert safety risks.
