The XS Power Li-S1600CK 16V lithium car audio battery bundles the proven Li-S1600 LFP cell with the hardware needed to get you from the workbench to the car without a trip to the hardware store. It carries all the credentials of a true competition audio battery — Group 34 sizing, LiFePO4 chemistry, and the kind of voltage stability that keeps amplifiers happy even at full tilt.For shops and enthusiasts who want a ready-to-mount high output SPL battery solution, the CK suffix means the hard parts are handled. The lightweight lithium battery design sheds meaningful mass versus lead-acid, and its deep cycle lithium endurance makes it equally at home as a daily-driven supplemental battery in a street build loaded with aftermarket amplifiers.This Listing Includes: (1) XS Power Li-S1600CK Group 34 16V Lithium LFP Car Audio BatterySpecifications Model Li-S1600CK Product Type Lithium Car Audio Batteries Voltage 16V BCI Group Size Group 34 Maximum Amps 2160A Energy 371Wh Lead-Equivalent Cranking Amps 1620A Lead-Equivalent Amp Hours 70.2Ah Cranking Amps 1080A Amp Hours 23.4Ah Rated Power 5000W Polarity L Warranty 1-Year — view warranty (PDF) UPC 692209053774 Package Length 12.5 in.
