Running a massive wall of subwoofers demands a battery that can sustain output without flinching, and the XS Power Li-S30 12V lithium car audio battery was built exactly for that challenge. This LiFePO4 battery brings a generous capacity in a form factor that fits common Group 30L applications, making it straightforward to drop into an existing build or secondary battery position. The low voltage drop characteristic of LFP chemistry means your amplifiers maintain consistent headroom even during the most intense bass hits.Whether you are hauling a full competition setup to shows on the weekend or running a high output SPL battery configuration in a dedicated build, the Li-S30 delivers the deep cycle lithium reliability that serious enthusiasts have come to expect from XS Power. At just over ten pounds for a battery offering this level of capacity, weight-conscious builders gain a meaningful advantage without compromising on the raw current delivery that separates a great system from an average one.This Listing Includes: (1) XS Power Li-S30 Group 30/30L 12V Lithium LFP Car Audio BatterySpecifications BCI Group Size Group 30/30L Volts 12V Max Amps 2050 CA 1200 CA Pb Eq 1800 Ah 22 Ah Pb Eq 66 Energy Wh 297 Wattage Support 6,000 Polarity Q Included Hardware M6 Hardware Included Warranty 1 Year — view warranty (PDF) Instructions Download instructions (PDF) Length (Inches) 8.98 Width (Inches) 6.45 Height (Inches) 8.94 Weight (lbs) 10.30 Weight (kg) 3.99 Available from JS Alternators.PROP 65 WARNING: This product can expose you to chemicals including lead and lead compounds, which are known to the State of California to cause cancer or birth defects or other reproductive harm.
