XS Power Li-S1600CK 16V Lithium Car Audio Battery
Many in-stock orders ship within 1-2 business days, but timing varies by item. Custom, built-to-order, oversized, special-order and supplier-direct products may need extra processing time. Free shipping applies to qualifying orders over $99 in the contiguous US. Approved returns may be subject to a restocking fee.
Most products are covered by the manufacturer's warranty against defects. Damage from over-powering or improper installation isn't covered — we'll help coordinate any valid claim.

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.
Kit Convenience for the Serious Builder
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.
