The XS Power XMAX 22 is a 12-volt lithium car audio battery built for enthusiasts running high-output amplifier systems in vehicles where mounting space is at a premium. Using lithium iron phosphate (LiFePO4) chemistry, it delivers stable voltage and fast charge/discharge response, well suited for SPL competition builds and daily-driven show systems.
Under load, the XMAX 22 supports up to 5,000 watts of burst SPL output and 2,500 watts of continuous music power, with a peak current of 2,050 amps. Its 22.5 Ah rating translates to roughly 66 Ah of PB EQ capacity versus a traditional AGM battery, giving it serious output in a compact form factor. The U1R BCI group size and 975R-compatible housing make it easy to integrate into trunk builds and factory trays.
At 7.8 lbs, the XMAX 22 uses a compact U1R group size and 975R-compatible housing for tight installations. It is intended as a supplemental battery and pairs best with additional xMAX units. If paired with AGM batteries, XS Power recommends using a battery isolator with AGM units less than one year old. A lithium-specific charger is required, and the battery is not rated for under-hood or marine applications.
