Matching the Group 20L form factor with genuine LFP battery output, the XS Power Li-PSX20Q 12V lithium car audio battery is engineered for the builder who needs both specific sizing and real power delivery. Strong max amps relative to its footprint and respectable capacity make it adaptable across a surprising range of applications, from motorcycle-based audio to compact competition builds.
Group 20L Size, Lithium-Class Performance
Coming in at 3.5 lbs, the Li-PSX20Q is the definition of a lightweight lithium battery — light enough to mount in nearly any orientation without stressing brackets, yet capable enough to function as a credible supplemental battery in modest amplifier systems. Its deep cycle lithium chemistry outlasts conventional batteries by a wide margin, and the stable LFP voltage means you will see minimal low voltage drop even when the system is working hard.
