{"product_id":"sb630-51r","title":"XS Power SB630-51R 630F 12V SuperBank Ultracapacitor","description":"\u003cp\u003eBuilt around the Group 51R footprint, the XS Power SB630-51R 12V SuperBank packs a full 630 farads of \u003cstrong\u003eultracapacitor\u003c\/strong\u003e capacity into a size that fits neatly in tight engine bays and compact front-battery locations. That massive farad rating means the SB630-51R can deliver enormous instantaneous current on demand, serving as a powerful \u003cstrong\u003evoltage stabilizer\u003c\/strong\u003e that keeps your system voltage stable when amplifiers slam into a low-frequency peak. Front-stage power, secondary support, or a clean replacement in an existing Group 51R slot — this unit handles all three scenarios.\u003c\/p\u003e\u003cp\u003eThe XS Power SB630-51R is an elite-grade \u003cstrong\u003eSPL capacitor bank\u003c\/strong\u003e that bridges the gap between a traditional \u003cstrong\u003epower cap\u003c\/strong\u003e and a full battery replacement. Its \u003cstrong\u003ehigh current capacitor\u003c\/strong\u003e cells charge and discharge with minimal internal resistance, which translates directly to crisper transient response from your subwoofers and a measurable improvement in system dynamics compared to a battery alone.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:35%;\"\u003eType\u003c\/td\u003e\n\u003ctd\u003e12-Volt Super Capacitor Bank\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:35%;\"\u003eGroup Size\u003c\/td\u003e\n\u003ctd\u003eGroup 51R (Reverse Terminals)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:35%;\"\u003eMax Power\u003c\/td\u003e\n\u003ctd\u003e5,000 Watts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:35%;\"\u003eCapacitance\u003c\/td\u003e\n\u003ctd\u003e630 Farads\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:35%;\"\u003eWeight\u003c\/td\u003e\n\u003ctd\u003eUltra Lightweight\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:35%;\"\u003eTerminal Hardware\u003c\/td\u003e\n\u003ctd\u003eM6 Terminal Hardware Included\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cstrong\u003eAuthorized XS Power dealer at JS Ultimate Sounds.
