Why Choose an LTO Battery for Car Audio?

Upgrading your amplifier and subwoofer increases the demand on your car’s electrical system. During a powerful bass hit, the amplifier can draw a large amount of current in a short time.

Why add a battery for car audio?

Your starter battery helps start the engine. Once it is running, the alternator supplies the vehicle’s electrical equipment and recharges the battery. The factory system is designed around the car’s original electrical needs; a powerful audio upgrade can place extra demand on the battery, alternator and wiring.

A suitably sized auxiliary battery can supply additional current during demanding passages and help reduce voltage drop. It does not replace the alternator: if the system uses more power than the alternator can continuously provide, the battery will eventually discharge.

Why choose LTO?

Lithium titanate (LTO) cells are known for low internal resistance, high charge and discharge capability, and long cycle life. These characteristics make LTO a compelling choice for car audio systems that face rapid changes in current demand.

For example, a Gree Altairnano (formerly Yinlong) LTO66160H 40Ah cell has a nominal voltage of 2.3V. Its published specification lists a 240A maximum continuous discharge current at 25±2°C. This is a single-cell specification, not a complete battery pack rating; connections, wiring and pack design also limit current.
