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.
Most products are covered by the manufacturer's warranty against defects. Damage from over-powering or improper installation isn't covered — we'll help coordinate any valid claim.

For builders who need Group 27 dimensions without sacrificing ultracapacitor performance, the XS Power SB1000-27 delivers 1,000 farads in a 12V sealed package that slots into a narrower tray footprint. The SuperBank design is identical in electrical behavior to its Group 31 counterpart — the same high current capacitor technology, just shaped to fit where a Group 27 lives.
Group 27 Fit, Uncompromised Voltage Stabilization
Headlight dimming and dynamic compression during heavy bass transients are the symptoms of a system calling for more current than the charging system can deliver instantly — the SB1000-27 answers that call. This SPL capacitor bank functions as an ideal complement to an AGM battery, buffering the instantaneous demands so your battery and alternator handle the sustained load while the ultracapacitor handles the peaks.
