Few lithium car audio batteries can claim the burst output figure that defines the XS Power xMAX 90, and fewer still combine that headline number with a 90Ah usable capacity that sustains high-draw systems through long sessions. The LiFePO4 / LFP chemistry is inherently safer and more stable than older lithium variants, and it holds voltage with remarkable flatness as the pack discharges — a characteristic that keeps amplifiers performing consistently from the first note to the last. At just over 26 pounds, it dramatically undercuts the weight of any lead-acid battery with comparable output.
20,000W Burst in a Manageable Package
Whether you are a competition audio builder chasing big SPL numbers or a serious daily driver running multiple high-power amplifiers, the xMAX 90 delivers where it counts. The low voltage drop characteristic of this deep cycle lithium platform means your system plays louder and cleaner on the same amplifier hardware.
