Sharing the same 1,260 farad ultracapacitor capacity as its Group 31 sibling, the XS Power SB1260-27 offers that same SPL capacitor bank performance in a Group 27 footprint — a meaningful option for builders whose vehicle layout or available tray space favors the slightly narrower form factor. The sealed 12V design is just as capable at voltage stabilization regardless of which group size fits your build.
Same Power, Different Footprint
When amplifiers pull heavy current faster than an alternator can respond, the SB1260-27 acts as the buffer — a high current capacitor bank that absorbs transient loads and prevents the headlight dimming and audible voltage sag that plague underpowered systems. Whether your build is chasing SPL competition scores or you simply want a refined daily-driver system that stays composed at high volume, this farad capacitor bank delivers.
