Description Specifications Up To 1800 Watt Amplifiers 12V AGM Battery, 75 AH The Stealth 750 from Stealth Energy by American Bass delivers the deep reserve power that demanding car audio systems need. With 75 amp-hours of capacity and support for amplifier setups up to 1800 watts, this sealed AGM battery is engineered to reduce voltage drop, maintain stable output during hard bass hits, and keep your system sounding clean — whether you're competing or just enjoying the ride. Designed specifically for car audio, the ST-750 uses Absorbed Glass Mat technology in a fully sealed, maintenance-free ABS housing. Mount it in virtually any position without worrying about spills, corrosion, or topping off fluids. A 900A max discharge current (5-second burst) and ultra-low 6.6mΩ internal resistance ensure fast power delivery when your amplifiers need it most. Why Choose the Stealth 750? The ST-750 sits in the sweet spot of the Stealth Energy lineup — enough capacity to anchor a serious multi-amplifier build without the weight and footprint of a full 100Ah battery. Use it as a dedicated secondary battery or as your primary power source for systems that demand more than a stock battery can provide.
