At the top of XS Power's Group 34 lithium car audio battery offerings, the Li-S3400 is engineered for competitors and enthusiasts who want maximum output from a standard battery footprint. Its LFP battery cells generate exceptional max amps — among the highest in the entire 12V lithium car audio battery segment — while maintaining the flat voltage delivery that separates true competition audio battery technology from the pack.
Group 34 Footprint, Flagship-Class Power
Whether anchoring a multi-battery SPL system or serving as a powerhouse primary cell in a high-output daily driver, the Li-S3400 earns its place. Its deep cycle lithium construction handles repeated hard draws without the degradation of lead-acid alternatives, and at under 20 lbs for its class it remains a genuinely lightweight lithium battery choice. Pair it with a matched high-output alternator for a truly low voltage drop platform.
