XS Power Vehicle Batteries: Performance-Engineered Power for Every Build

When a vehicle's electrical system is pushed to its limits — whether on the drag strip, the show floor, or a diesel-powered work truck — the battery becomes the foundation of everything. XS Power Batteries has been engineering high-performance vehicle batteries since 2005, building a reputation on rigorous in-house and third-party lab testing to back up every specification printed on their labels.

What separates XS Power from off-the-shelf alternatives is a multi-chemistry approach to vehicle power. Rather than offering a single technology, XS Power gives builders and enthusiasts a targeted solution for their specific power demands — from everyday reliability to extreme competition use.

The XS Power Vehicle Battery Lineup

D-Series, S-Series & PS-Series AGM Batteries form the backbone of the XS Power catalog. These AGM (Absorbed Glass Mat) batteries feature a sealed design where glass fiber mats contain the acid electrolyte between the lead plates, eliminating the risk of leaks even in rough or inverted installations. They deliver higher cranking amps than OEM batteries, exhibit lower internal resistance than conventional lead-acid units, and are built to handle high electrical loads without voltage sag. The PS-Series adds extra-rugged casing for off-road and racing environments where shock and vibration resistance are critical.

Titan8-Series (LTO) represents XS Power's lithium flagship. Using Lithium Titanate Oxide (LTO) cell chemistry, the Titan8 is designed to be underhood-safe and offers a compelling balance of light weight, energy density, and massive burst output. The lineup splits into two sub-series: the PWR-Series optimized for serious burst capacity, and the RSV-Series focused on extended reserve capacity and deep cycling. The RSV LTO batteries are designed for high-burst output of up to 12,000 watts in short bursts, with enhanced reserve capacity for sustained demands.

xMAX-Series batteries are purpose-built for the most extreme car audio and high-draw applications. The xMAX line supports anywhere from 7,000 to well over 16,000 watts using a single battery, operating at up to 14.8 volts — making it compatible with stock alternators or performance aftermarket units.

SuperBANK Ultracapacitors round out the vehicle power ecosystem. These capacitor banks offer instantaneous high-energy surges ideal for starting applications and for smoothing voltage demands from large amplifier systems, with the smallest units starting at 1,500 amps of peak current.

Why XS Power Stands Out in Vehicle Batteries

• Available in 12V, 14V, and 16V configurations to match a wide range of charging systems and performance builds
• Sealed, maintenance-free AGM design that resists leaks, vibration, and extreme temperatures
• Lower internal resistance than traditional flooded batteries, meaning more usable power with less heat waste
• Multiple series covering daily drivers, diesel trucks, race cars, and competition audio builds
• Drop-in replacement fitment across standard BCI group sizes for easy installation
• Backed by in-house and accredited third-party lab testing to verify rated specifications

Whether you're replacing a worn starting battery on a daily driver, adding auxiliary power to a diesel build, or chasing a sound pressure level record, XS Power's vehicle battery lineup offers a purpose-matched solution.
