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

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
