Shop Lithium Pros at JS Ultimate Sounds — American-built lithium (LiFePO4) batteries and chargers engineered for motorsports, car audio and powersports, where weight savings and consistent voltage under load both matter.

Lithium Pros Batteries

Lithium Pros batteries deliver far more usable capacity than lead-acid at a fraction of the weight — typically around 60% lighter than a comparable AGM. For audio builds that translates to voltage that holds up between bass hits; for motorsports it's weight out of the car without giving up cranking power. Browse the full Lithium Pros lithium battery range.

Lithium Pros Chargers

LiFePO4 chemistry needs a charger designed for it — voltage profiles and cutoffs differ from lead-acid, and using the wrong charger shortens battery life or trips the BMS. Shop matched Lithium Pros battery chargers to keep a pack properly maintained between uses.

Before You Buy Lithium

Two things every lithium buyer should know: a proper BMS is required to prevent overcharging, and charging a lithium battery directly from an alternator can spike voltage when the BMS cuts off — a DC-DC charger between the two solves it. Full detail in our lithium vs AGM guide.
