Fitting a Group 27 battery location, the XS Power SB500-27 12V SuperBank brings 500 farads of true ultracapacitor storage to full-size vehicle platforms that have the space for a larger footprint. That capacitance level puts it squarely in SPL capacitor bank territory, capable of absorbing and releasing energy faster than any lead-acid or lithium battery can manage alone. Truck and SUV builds with room for a Group 27 position will find the SB500-27 a natural upgrade that stops headlight dimming and firms up bass transients without adding excessive mass.
The XS Power SB500-27 is a premium farad capacitor bank that complements rather than replaces your primary battery, teaming up with your existing charging system to deliver on-demand current when amplifiers spike. Its high current capacitor chemistry holds up under the repetitive discharge cycles of a show season far better than outdated stiffening capacitor designs, making it a smarter long-term investment for serious car audio enthusiasts.
