Stealth 200 — 20Ah AGM Car Audio Battery for Entry-Level & Secondary Power

The Stealth 200 is the compact powerhouse in the Stealth Energy lineup by American Bass. With 20 amp-hours of capacity and support for amplifier setups up to 700 watts, this sealed AGM battery is built for enthusiasts who need clean, reliable power without the size and weight of a full-size battery. At just 12.7 lbs, it fits where other batteries can't — making it the go-to choice for tight installs, secondary battery setups, and single-amp systems that need more than a stock battery can deliver.

Featuring Absorbed Glass Mat technology in a fully sealed, maintenance-free ABS enclosure, the ST-200 can be mounted in virtually any position with zero risk of spills or corrosion. A 300A max discharge current (5-second burst) provides the instant power your amplifier demands during hard-hitting bass passages, while the compact 7.14" × 3.03" × 6.59" footprint makes it easy to tuck behind seats, in trunks, or in custom enclosure builds.

Why Choose the Stealth 200?

Not every build needs a 75Ah or 100Ah battery. The ST-200 is purpose-built for single-amplifier systems, smaller upgrades, and secondary power applications where space and weight matter. It's also an excellent option for powering car audio accessories, emergency backup systems, and other 12V applications that need dependable AGM performance in a small package.
