XS Power SB630-51R

12-Volt Super Capacitor Bank Group 51R (Reverse Terminals) Max Power: 5,000 Watts 630 Farads Ultra Lightweight M6 Terminal Hardware Included The XS SuperBANK is perfect for high-power car audio systems, engine starting systems, and more. Connect multiple cells together to make a customized power pack, delivering the perfect amount of energy on demand so your amps, battery, or engine gets every bit of power they need—whenever they need it. The SB630 delivers a surge of power to the factory 12-volt battery as it cranks, then it rapidly recharges (usually in only a few seconds), ready to use again. The improved voltage conditions lead to longer-lasting factory batteries, starters, relays, and engine control modules, improving reliability and lowering the likelihood of costly repairs. Ultracaps also work extraordinarily well in extreme hot or cold. In winter, the Ultracap delivers a much-needed burst of energy to vehicles using a typically slow-cranking AGM battery. Rated to more than a million cycles, the Ultracap is designed to work well in commercial vehicles or “daily drivers”, normally lasting more than a decade. See specifications below.
