About this part

The Onisiki Aluminum Case Hyper Booster Capacitor delivers specs matched perfectly for high powered brushless systems. Wrapped in an aluminum case for efficient cooling and consistent performance, this capacitor helps deal with voltage sag during hard acceleration. With very low internal resistance the charge/discharge rate is very high making it perfect for race applications and drift cars. The maximum voltage which this cap can take is 9v, allowing it to help stabilize voltage spikes and remain compatible with HV batteries.
