Overview
In a trunk-mounted battery bank for car audio or racing, the XS Power supplemental battery adds capacity alongside the main battery. Its sealed, spill proof AGM design mounts in almost any position and resists vibration.
Very low internal resistance lets it deliver current fast to amplifiers during bass peaks. It is not designed for under-hood use, so it cannot replace a starting battery.
Who it's for
Competition audio systems and race cars needing extra reserve suit it. Daily drivers needing a stock replacement should buy a standard starting battery.
Pros and cons
- Sealed, spill proof AGM
- Mounts in almost any position
- Low internal resistance
- Not for under-hood use
- Small capacity for large systems
Performance notes
Glass mat construction holds the electrolyte in fiberglass, which is why it can sit at odd angles without leaking. Low internal resistance means voltage drops less under heavy, short bursts of current.
