The Cayote Crest ESC External Low ESR Capacitor is designed to reduce voltage spikes and electrical noise on the ESC power line, helping protect sensitive electronics in high-performance RC applications. It mounts externally and connects via the included red and black lead wires, making installation straightforward without modifying the ESC itself. Low ESR capacitors are a common upgrade or replacement for racers looking to stabilize power delivery from the battery to the ESC. Features: External mount design connects directly to ESC power leads Low ESR construction for reduced voltage spike interference Includes pre-soldered red and black wire leads Compatible with a wide range of 1:10 scale electric platforms 7/7/26 cs
