The new PowerTank Lithium keeps the charge going for the astronomer on the go. The Lithium Phosphate (LiFePO4) battery chemistry has significant advantages over other battery chemistries.


  • The LiFePO4 has an un-recharged shelf life of 10 years compared to 3 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.


This combined with it’s rugged design make it the perfect outdoor power supply.

Keep your telescopes, smartphones, tablets, GPS systems, cameras and other USB-powered devices as active as you are with PowerTank Lithium—the ideal outdoor portable-charging solution for your electronic gear.



  • Portable power pack for your computerized Celestron telescope using Lithium Iron Phosphate (LiFePO4) chemistry

  • Smaller, lighter, safer, and easier to maintain than lithium-ion and sealed lead acid designs

  • Up to 2000 charge cycles – four times more than lithium-ion & 7 times more than sealed lead-acid designs.

  • Un-recharged shelf life of up to 10 years – 3 times better than lithium-ion and 10 times better than sealed lead-acid designs
