This capacitor module (/cappack) is for “upgrading” your car ESC. With this cappack, 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. Key Features: Low impedance, low heat generation, great start-up acceleration. The comparison between HobbyWing capacitor module and some famous 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. Specification: Capacity: 560µf x 3 Voltage endurance: 20V Internal resistance: 0.002Ω Ripple current endurance: 24Amp Wight: 6g Applications: XERUN XR10 PRO, XERUN XD10
