LF-G31-80HP High-Power Car Audio Lithium Battery
80Ah A123 high-power lithium platform engineered for professional car audio, SPL competition, distributors, brands and custom installers. Built around extreme current delivery, ultra-low assembled resistance and a Group 31 form factor.
PRODUCT OVERVIEW
Built for Current. Not Just Capacity.
High-power car audio systems do not just need stored energy — they need current delivered fast. LF-G31-80HP combines an 80Ah A123 cell platform with up to 4,800A burst current and ≤1.5mΩ fully assembled ESR.
Designed for 15,000–20,000W RMS daily music systems and competition-oriented SPL applications up to 40,000W MAX under defined system and test conditions.

Built for high-current audio:
Unlike a standard deep-cycle lithium battery, LF-G31-80HP is focused on rapid current delivery, low impedance and voltage support during demanding transient loads.
*System power and burst ratings depend on system voltage, amplifier efficiency, alternator output, wiring, load duration, state of charge and test conditions.
