The XS Power SB1260-31 SuperBank brings 12V ultracapacitor technology to the Group 31 form factor, offering a massive farad capacitor bank that integrates cleanly into the standard battery tray locations used in most competition and street vehicles. Its 1,260 farad capacity positions it as a top-tier power cap for systems where voltage stability under load is non-negotiable.
Group 31 Format, Competition-Grade Capacitance
Unlike a standard battery that struggles to respond to fast transient current demands, this high current ultracapacitor bank charges and discharges at near-instantaneous rates, acting as a surge reservoir that keeps amplifier voltage rock-steady through every bass note. The SB1260-31 is the solution for SPL competitors and serious daily-driver enthusiasts alike who want to stop headlight dimming and voltage sag without sacrificing installation simplicity.
