New Lithium Phosphate (LiFePO4) portable power pack from Celestron designed to keep your telescopes, smartphones, tablets, GPS systems, cameras and other USB-powered devices powered and charged. The ideal outdoor portable-charging solution for your electronic gear.


  • Portable power pack for your computerised 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
  • Environmentally friendly – Does not use toxic heavy metals
  • 86.4 Wh equivalent to approximately 7.2Ah when running at 12v

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.

A power charge was needed for my Virtuoso mount and it had to be very portable and as environmentally green as possible for a battery. In addition I choose this powertank because it was very compact and light. If I get 2,000 charge cycles then that is less than 0.07GBP every time I use it plus with the advantage it does not need to be recharged after each use. So far it has been outside in 2-3 degrees for about 1.5 hours each time running a mount using slewing and it is still 75% charged. It is kept in a handy location just in case there is a house power cut as it would be very useful with it's red/white lights and two usb ports. If I needed to run dew heaters I would need another power solution.
