{"product_id":"sb860-31","title":"XS Power SB860-31 860F 18.9V SuperBank Ultracapacitor","description":"\u003cp\u003eAn 860-farad ultracapacitor bank in a Group 31 form factor — the XS Power SB860-31 SuperBank is a serious piece of equipment for builders who have moved past conventional power caps and want real farad capacity working for their system. Unlike a standard one- or two-farad capacitor, the SB860-31 stores enough energy to genuinely buffer voltage during heavy bass transients, functioning more like a lightning-fast secondary battery than a simple filter component.\u003c\/p\u003e\u003cp\u003eThe practical result is dramatic: headlights stop dimming, amplifier rails stay stable, and the dynamic headroom of the entire system improves — especially noticeable on high-excursion bass notes that would normally cause a voltage dip. As an SPL capacitor bank and voltage stabilizer , the SB860-31 is sized right for daily-driver builds with large amplifier loads and for competitors who want a compact, self-contained farad capacitor bank that fits neatly into the existing electrical layout without requiring a complete overhaul.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThis Listing Includes:\u003c\/strong\u003e (1) XS Power SB860-31 860F 18.9V SuperBank Ultracapacitor\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:35%;\"\u003eModel\u003c\/td\u003e\n\u003ctd\u003eSB860-31\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:35%;\"\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eUltracapacitor Banks\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:35%;\"\u003eVoltage\u003c\/td\u003e\n\u003ctd\u003e18.9V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:35%;\"\u003eBCI Group Size\u003c\/td\u003e\n\u003ctd\u003eGroup 31\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:35%;\"\u003eMaximum Amps\u003c\/td\u003e\n\u003ctd\u003e20000A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:35%;\"\u003eEnergy\u003c\/td\u003e\n\u003ctd\u003e42.4Wh\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:35%;\"\u003eCapacitance\u003c\/td\u003e\n\u003ctd\u003e860F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:35%;\"\u003eRated Power\u003c\/td\u003e\n\u003ctd\u003e8000W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:35%;\"\u003ePolarity\u003c\/td\u003e\n\u003ctd\u003eL\/R\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:35%;\"\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e1 year\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:35%;\"\u003eUPC\u003c\/td\u003e\n\u003ctd\u003e810111135214\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:35%;\"\u003ePackage Length\u003c\/td\u003e\n\u003ctd\u003e15.28 in.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:35%;\"\u003ePackage Width\u003c\/td\u003e\n\u003ctd\u003e9.25 in.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:35%;\"\u003ePackage Height\u003c\/td\u003e\n\u003ctd\u003e11.5 in.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:35%;\"\u003ePackage Weight\u003c\/td\u003e\n\u003ctd\u003e25 lbs.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp\u003e\u003cstrong\u003eAvailable from JS Alternators, an authorized XS Power retailer.\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003ePROP 65 WARNING: This product can expose you to chemicals including lead and lead compounds, which are known to the State of California to cause cancer or birth defects or other reproductive harm.
