Competition builds and extreme daily systems often move to 16V so amplifiers see a higher supply voltage on every note. These 16 volt car audio batteries from XS Power include AGM models such as the D1600, D16-31, S1600 and XP1000, plus lithium and lithium titanate options like the Li-D1600, Li-S1600, PWR-S7-1600BMS and RSV-S7.
Plan the charging and equipment side before ordering.
A 16V bank can let amplifiers rated for the higher voltage make more power, but it changes the whole electrical plan. The batteries need a charging source designed for 16V, either a dedicated 16V alternator or regulator setup, or a 16V charger used between sessions. Most factory electronics are designed around a 12V system, so many builds keep 16 volt car audio batteries on a separate audio circuit, isolated from the vehicle's starting and accessory system.
Confirm the maximum input voltage of every amplifier, processor, capacitor and accessory on the 16V side. Equipment that is not rated for it can shut down or fail. Use fuses, cable and connectors appropriate for the current your amplifiers draw, and size wire gauge for both current and run length.
XS Power 16V AGM batteries, including the D1600, D16-31, S1600 and XP1000, are sealed and spill resistant and suit builds that want a familiar lead-acid chemistry. The lithium side includes the Li-D1600, Li-D1600XR, Li-S1600, Li-S925-16 and Li-S680-16 racing batteries, the RSV-S7 and RSV-S7-1600 lithium titanate models, and the PWR-S7-1600BMS. Lithium options generally weigh less and hold voltage higher under load. Choose between the two by weight, space and how the bank will be charged.
Keep 16 volt car audio batteries charged with a unit rated for 16V and the matching chemistry from our chargers collection; ordinary 12V chargers are not built to finish the job. Compare 14 volt batteries if you want a smaller step up from stock voltage. High-output alternators configured for 16V output keep the bank up during long sessions, 1/0 AWG power wire carries the main current, and the full electrical department covers fuses and terminals.
