The Lithium Phosphate (LiFePO4) battery has significant advantages over other battery chemistries...

  • The LiFePO4 has an un-recharged shelf life of 10 years compared to three years for the Lithium Ion and 6-9 months for a Sealed Lead-Acid battery.
  • The battery performance of the PowerTank Lithium degrades at a much slower pace than other chemistries.
  • The LiFePO4 can be charged and discharged 2000 times compared to only 500 for a Lithium Ion battery and 300 for sealed lead-acid designs.
  • The batteries will last as long as the telescope you use it with!
  • The LiFePO4 uses phosphates instead of environmentally hazardous elements like cobalt or lead commonly found in other rechargeable batteries.
  • Can withstand higher temperatures than lithium-ion designs and will not be a fire danger if accidentally punctured.
  • Rugged design make it the perfect outdoor power supply.
