Stealth 150 — 15Ah AGM Car Audio Battery for Compact Installs & Entry-Level Power

The Stealth 150 is the most compact battery in the Stealth Energy lineup by American Bass — built for enthusiasts who need clean, dedicated 12-volt power without eating up valuable install space. With 15 amp-hours of capacity and support for amplifier setups up to 500 watts, this sealed AGM battery is the easiest way to add a secondary power source to your car audio system and start hearing the difference that stable voltage makes.

At just 10.8 lbs and a slim 7.14" × 3.01" × 6.59" footprint, the ST-150 fits where other batteries simply can't — behind seats, under panels, inside custom enclosures, or tucked into a motorcycle or powersports application. Absorbed Glass Mat technology in a fully sealed, maintenance-free ABS housing means you can mount it in any orientation with zero risk of spills, leaks, or corrosion. A 225A max discharge current (5-second burst) delivers the instant power your amplifier needs during peaks and transient bass hits.

Why Choose the Stealth 150?

The ST-150 is the entry point to dedicated car audio power. If you're running a single amplifier in the 300–500W range and your stock battery is struggling to keep up — lights dimming on bass hits, voltage sagging at high volume — the Stealth 150 solves the problem at the lowest cost and smallest footprint in the lineup. It's also an excellent choice for motorcycle audio, powersports rigs, alarm and security systems, emergency lighting, and any 12V application that needs reliable, compact AGM performance.
