Yeah Racing Hyper Booster ESC capacitor

Coming from Yeah Racing is their new Hyper Booster aluminium case capacitor for competition speed controllers. This capacitor helps to deal with voltage sag during hard acceleration, and thanks to a very low internal resistance the available charge/discharge rates are very high, making it perfectly suited for touring cars or drifters. The capacitor is housed in a machined aluminium case for cooling purposes and it is usable with up to 9V input voltage.
