Celestron Lithium PowerTank

Celestron Lithium PowerTank

At just 2.25lbs and 7.5" tall this unit can attach to the tripod easily, extremely light and portable making it ideal for travelling with your telescope as well as convenient for backyard use without cables trailing .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 making it a real long term solution for powering a telescope. The LiFePO4 uses phosphates instead of environmentally hazardous elements like cobalt or lead commonly found in other rechargeable batteries. Other significant advantages include an ability to withstand higher temperatures than lithium-ion designs and will not be a fire danger if accidentally punctured.

Customer Reviews

  Solid battery  I have had this a couple of weeks now and tried it out on my Celestron 130SLT. It is a sturdy but fairly compact battery with easy to access controls. The actual push buttons are under a cover to protect them from moisture whilst there is a power socket on the outside. It has stood up to the cold.  (22/02/2019) SRN - Derbyshire


  More than just a telescope accessory  Great service from Harrison Telescopes, with quick response to email question and next day delivery. Definitely an improvement over the 'car battery' type. Shame it doesn't have the cigarette-lighter socket, but it works just fine. Also handy for camping as a light and high capacity phone charger.   (12/10/2018) Paul - Kent


  Nice battey  Used this a few times now and it copes very well and easily managed a couple of evenings with the advanced VX mount. Leg strap works well and holds securely once you get the knack of tightening it.   (01/08/2018) Bob - South Wales


    Nice piece of kit ,much better than my old starter type ,its good that it can be strapped to the leg of telescope so being out of way .Delivery was very prompt.   (13/07/2018) Peter - Middlsex


  Just great. Seems fine  I have only tried it indoors todate, but it seems to be fine. Much better than my old "tank" Just need some clear nights before the light nights. I have to say, that I do not find the tripod leg strap very good. I have not get got it to hold properly   (04/04/2017) gkw - gtr.manchester


  Small and powerful  Surprised how small it is - runs my CPC easily and seems to last the whole evening even in cold weather, much better than the old jump starter types. geat power supply and delivered next day to Newcastle   (28/02/2017) Pete rS Randall - Newcastle
