Many in-stock orders ship within 1-2 business days, but timing varies by item. Custom, built-to-order, oversized, special-order, and supplier-direct products may need extra processing time. Free shipping applies to qualifying orders over $99 within the contiguous US. Freight items may require delivery coordination; any shipping exceptions are shown before checkout. Approved returns may be subject to a restocking fee.

The XS Power SB75-5 12V SuperBank is the entry point into the SuperBank ultracapacitor ecosystem, bringing 75 farads of genuine ultracapacitor performance to builds that are just beginning to explore capacitor-based power augmentation. Unlike older cylindrical stiffening caps that offered fractional farad ratings and poor ESR, the SB75-5 delivers a meaningful farad capacitor bank contribution that produces audible improvements in bass tightness and headlight stability. It is a real upgrade, not a novelty accessory.
Without a fixed group footprint, the XS Power SB75-5 is positioned for custom-mounted applications, supplemental secondary locations, or builds where the primary battery is fine but a dedicated car audio capacitor buffer near the amplifier would sharpen performance. As a high current capacitor unit at an accessible price point, it also makes a logical starting point for someone building toward a larger SuperBank installation, proving out the technology before committing to a full Group-sized bank.
