Overview
The Castle Creations 8S CapPack 2240uF / 35V (011-0148-00) is a high-voltage capacitor pack designed to improve electrical stability and protect ESCs in demanding 8S LiPo brushless RC systems. By absorbing voltage spikes and reducing electrical noise, the CapPack helps ensure smoother, more reliable power delivery under extreme load.
The CapPack adds 2240 microfarads of capacitance directly to the ESC power circuit, helping smooth out the voltage ripple created by rapid throttle changes and heavy current draw. This reduces stress on ESC components, improves efficiency, and can extend the overall lifespan of your power system.
Rated at 35V, the 8S CapPack is purpose-built for high-voltage configurations - ideal for large-scale vehicles, speed-run builds, high-KV motor setups, and any application where stock ESC capacitors may not be enough.
