Designed for increasing the average voltage during a cell discharged and lower the internal resistance of battery. Digital LC display the rading of the battery and capacitor voltage. High volume capacitance gives your battery woth lower resistance, more punch and acceleration that provide best performance for racing. Easier drag installation for the battery connecting. For both Nicd and NiMH battery type. Specifications: Input voltage: DC 12V Output voltage: DC 85V (SC type battery)
