{"product_id":"sb150-30q","title":"XS Power SB150-30Q 150F 12V SuperBank Ultracapacitor","description":"\u003cp\u003eDesigned around the Group 30L battery envelope, the XS Power SB150-30Q 12V SuperBank provides a direct-fit \u003cstrong\u003eultracapacitor\u003c\/strong\u003e solution for vehicles that use this less-common but widely available group size. With 150 farads of \u003cstrong\u003ecar audio capacitor\u003c\/strong\u003e capacity, it provides meaningful transient buffering that helps amplifiers maintain voltage stability during heavy bass hits, reducing headlight dimming and preserving sound quality under load. The Group 30L form factor makes the SB150-30Q a unique and valuable option for builds where other SuperBank sizes would require a bracket or custom tray.\u003c\/p\u003e\u003cp\u003eThe XS Power SB150-30Q operates as a \u003cstrong\u003ehigh current capacitor\u003c\/strong\u003e bank rather than a battery, meaning it focuses entirely on rapid charge and discharge cycles rather than sustained energy delivery. This makes it the ideal partner for a properly sized AGM battery in applications where the load profile is dominated by short, intense amplifier transients rather than long, sustained draws. A smart, targeted upgrade for the right vehicle platform.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAuthorized XS Power dealer at JS Ultimate Sounds.
