Capacitors store up power from your battery, then release it to your system during peak demand for more consistent draw of current. They are often used as a buffer between your battery's reserve capacity and the electrical system to preserve longevity of your equipment!

XS Power SB500-65 12V BCI Group 65, Super Capacitor Bank, Max Power 4,000W, 500 Farad
12-Volt SuperBank Ultracapacitor Group 65 Max Power: 4,000 Watts Voltage Range: 12.0 – 16.2 500 Farads 11 lbs. M6 Terminal Hardware Included The XS Power SuperBANK is perfect for high-power car audio systems, engine starting systems, and more. Connect in parallel with any lithium or AGM battery 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 SB500 delivers a surge of power to the factory 12-volt battery as it cranks, then rapidly recharges (usually in only a few seconds), ready to use again. The improved and stabilized voltage leads to longer-lasting factory batteries, starters, relays, and engine control modules, improving reliability and lowering the likelihood of costly repairs.Ultracaps (aka Supercapacitors) 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.12V BCI Group 65, Super Capacitor Bank, Max Power 4,000W, 500 Farad
