Elite Acoustics Engineering produces Battery Powered Amplifiers using two different type of batteries,

  1. Lithium Iron Phosphate (LifePO4) powered
  2. Shielded Lead Acid (SLA) powered

LifePO4 batteries have much longer shelf life then the SLA (Shielded Lead Acid) type of battery and is consider the safest type of Lithium battery. LifePO4 batteries can also supply much more current then the SLA type battery enable for a higher wattage amplifier. While the 12V9A SLA battery (used on our older generation amplifiers) can supply about 3A of maximum current, with the LifePO4 design we incorporated, 10A or higher can be achieved for our Amplifiers.More details on LifePO4 battery can be found on this link. LifePO4 battery.

SLA is available widely at a very reasonable price and it is very stable.

We choose Lithium Iron Phosphate (LifePO 4) type of batteries for it’s advantages in safety properties and Long service life. LifePO4 is thermally and chemically stable, reliable without the possibility of lithium fires. LifePO4 batteries have long service life, with a shelf life that far exceeds the service life of many other batteries. For more protection again mishaps, we added many Battery Protection circuits – Over Voltage protection, Thermal Shutdown, Over Charge protection, Over Drain protection. The LifePO4 batteries sused in our amplifiers are UL safety approved and MSDS certified
