The XS Power US1100-31 is a Group 31 lithium car audio battery built on LiFePO4 / LFP chemistry for competitors and enthusiasts who refuse to compromise on power delivery. Compared to conventional AGM batteries, this lightweight lithium battery dramatically cuts dead weight while supplying rock-solid voltage under the heaviest amplifier loads — exactly what SPL competitors demand from a high output SPL battery.
Deep-Cycle Performance for Daily and Competition Builds
Whether you are running a single big amplifier in a daily driver or stacking power in a dedicated competition audio battery slot, the US1100-31 holds voltage where it counts. Its deep cycle lithium design gives it excellent charge acceptance, and the low voltage drop battery behavior means your amplifiers stay happy even during extended listening sessions. A proven choice as a primary or supplemental battery in any serious car audio system.
