This is a Hobbywing Module-XS Modified/Stock Non Polarity Capacitor Module. A capacitor module is for “upgrading” your car ESC. With this capacitor the start-up acceleration of your vehicle will be greatly improved. Besides, the great ripple current endurance significantly reduces the generated interference due to the rapid ON/OFF of the ESC power tube. Features: Low impedance, low heat generation, great start-up acceleration. The comparison between HOBBYWING capacitor module and other established brand's capapack. With the great ripple current endurance, the interference generating from turning on/off of your ESC power tube is remarkably reduced. With the small size and light weight, it’s easy to install. Specifications: Size: Standard (1/10th) PN：86030005 Capacity: 1700µf
