XS Power Batteries

XS Power Batteries: Engineered for Extreme Power Demands

When it comes to performance batteries, few names carry the weight of XS Power Batteries. Founded in 2005, the brand has spent nearly two decades obsessing over one thing: delivering more power, more reliably, than any other battery on the market. Whether the application is a competition car audio build, a drag strip race car, a diesel truck, or a powersports vehicle, XS Power's battery lineup is purpose-built to handle electrical demands that would overwhelm ordinary batteries.

A Multi-Chemistry Approach to Performance

What sets XS Power apart in the battery category is its commitment to offering the right chemistry for every application. Rather than a one-size-fits-all approach, XS Power engineers products across three distinct technologies:

• AGM (Absorbent Glass Mat): The cornerstone of the XS Power lineup. The flagship D-Series and S-Series AGM batteries feature a sealed design that uses glass fiber mats to contain the acid electrolyte between the lead plates — eliminating leaks entirely and enabling mounting in virtually any orientation. These batteries deliver higher cranking amps than OEM units, lower internal resistance than traditional lead-acid designs, and maintenance-free operation that holds up in extreme temperatures, vibration, and shock environments common to racing and off-road use. The XP-Series extends AGM technology into marine and auxiliary applications, offering deep reserve capacity, while the PS-Series targets powersports riders needing rugged, high-cranking AGM power in compact form factors.
• LTO — Lithium Titanate Oxide (Titan8 Series): XS Power's most advanced battery platform. The Titan8 is available in 12V, 14V, and 16V configurations, and splits into two sub-lines: the PWR-Series (Power Series) for serious burst capacity and the RSV-Series (Reserve Series) for enhanced deep cycling and longer life. Titan8 batteries deliver up to 7,000 watts of burst power and feature built-in bussing for simplified installation. LTO chemistry also makes the Titan8 exceptionally safe and recoverable — even a deeply discharged unit can be brought back to life with an XS Power IntelliCharger.
• LFP — Lithium Iron Phosphate: For those seeking dramatic weight savings without sacrificing energy storage, XS Power's LFP batteries offer a lightweight profile with fast charging and high energy density. The PS-Series LFP variants are especially well-suited for motorcycles, ATVs, personal watercraft, and UTVs where every pound matters.
• xMAX Series: Built from the ground up for extreme car audio, the xMAX line supports system demands ranging from 7,000 watts all the way up to 30,000 watts from a single battery — one of the most capable lithium powercell platforms available for competition-grade builds.

What Makes XS Power Batteries Different

XS Power backs every product claim with rigorous testing. The brand operates an in-house testing laboratory and also engages third-party accredited labs to verify performance specifications before any product reaches the market. This commitment to verified performance has earned XS Power a dominant presence in sanctioned audio and racing competition worldwide.

Across all chemistries, XS Power batteries share several key design traits: sealed, leak-proof construction that XS Power guarantees even if the housing is physically damaged; vibration and shock resistance engineered for race track and off-road abuse; and maintenance-free operation that requires no fluid checks or top-offs over the life of the battery. Available in a wide range of BCI group sizes, XS Power batteries are designed as true drop-in replacements for most factory battery positions, as well as scalable auxiliary power solutions for high-demand electrical systems.
