The XS Power S545 12V AGM battery is the most compact unit in the S-series lineup, but it carries the same engineering philosophy that defines the entire range: genuine sealed-AGM construction, real deep-cycle capability, and build quality that outlasts conventional alternatives. It is ideal for powersports audio, motorcycle sound systems, and the auxiliary battery positions in custom car builds where every inch of clearance counts.
The Smallest S-Series, Still Built Like an XS Power Battery
Do not mistake compact dimensions for limited ambition — the S545 handles the charge and discharge cycling of an active amplifier system the way a quality AGM battery should. Its lightweight design and extended warranty make it attractive for weight-conscious builds such as performance vehicles running minimal audio, while the spillproof construction removes the installation constraints that come with flooded chemistry at this size. A focused, dependable tool for specific applications.
