Designed and engineered by Traxxas, the XL-2.5 Electronic Speed Control delivers smooth throttle control in 1/16 scale and smaller models, and is completely waterproof for all-weather R/C driving fun. This high-performance ESC is packed with impressive specifications that are normally only found on more expensive high-end replacement units. The XL-2.5 features three throttle profiles, Thermal Shutdown Protection, 6-8 cell NiMH and 2-cell LiPo compatibility, and built-in BEC. High-frequency operation combined with ultra-low resistance make the XL-2.5 an efficient and ultra-smooth fully proportional speed control. XL-2.5 is equipped with two-stage low-voltage detection (LVD) to allow LiPo battery use.
