The XS Power xMAX 45 proves that enormous power potential does not require enormous size. Packing a serious burst current rating and 45Ah of usable LiFePO4 / LFP capacity into a chassis under 15 pounds, this lightweight lithium battery opens up secondary and supplemental placement options that are impossible with traditional battery technology. Compact cars, off-road vehicles, and builds constrained by trunk real estate finally have a competition audio battery option that fits their space without sacrificing electrical headroom.
10,000W Burst for Focused Builds
This lithium car audio battery excels when paired with a strong alternator in a one- or two-amplifier system that demands reliable voltage stability at peak power. The deep cycle behavior of LFP chemistry means the xMAX 45 recovers quickly between runs and delivers consistent performance whether you are running an SPL competition or simply enjoying your daily commute at reference levels.
