Up To 900 Watt Amplifiers

12V AGM Battery, 35 AH

Stealth 350 — 35Ah AGM Car Audio Battery for Mid-Range Systems

The Stealth 350 is the mid-range workhorse of the Stealth Energy lineup by American Bass. With 35 amp-hours of capacity and support for amplifier setups up to 900 watts, this sealed AGM battery hits the balance point that most car audio builds actually need — enough reserve power to eliminate voltage sag and keep your amplifiers performing at their best, in a package that's still compact enough for flexible mounting.

Built with Absorbed Glass Mat technology inside a fully sealed, maintenance-free ABS enclosure, the ST-350 delivers clean, stable 12-volt power with no risk of spills, leaks, or acid corrosion. A 525A max discharge current (5-second burst) and low 11mΩ internal resistance mean fast, efficient power delivery right when your system demands it — on transient bass hits, sustained low notes, and everything in between.

Why Choose the Stealth 350?

The ST-350 is the most versatile battery in the Stealth Energy range. It's large enough to serve as the sole dedicated audio battery for a single high-powered amplifier or a modest two-amp setup, yet at 24.7 lbs and a 7.68" × 5.12" × 6.57" footprint, it's still easy to fit into trunks, behind seats, or alongside custom enclosures. If you've outgrown a basic setup but aren't ready for a full 55Ah or 75Ah build, the Stealth 350 is the smart next step.
