Home Accessories Celestron Accessories Celestron Lithium PowerTank
The Lithium PowerTank keeps the charge going for the astronomer without the hassle of old technology and heavy battery packs. The Lithium Phosphate (LiFePO4) battery chemistry has significant advantages over other battery chemistries. This portable clean solution to powering a computerised telescope in the field uses a greener more practical design than traditional batteries, a versatile power source for a variety of electical products. Telescope Lead IncludedThe supplied 2 meter power lead is suitable for Celestron 12v telescopes as well as many SkyWatcher models that use the 2.1mm centre positive plug / socket. Even from completely flat the Lithium PowerTank takes only three hours to be fully charged.Lightweight and Long LastingAt 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.
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.Included Items Battery pack AC mains charger Power cord for Celestron telescopes Strap for attaching to tripod Strap for hanging The compact rugged design make it the perfect outdoor power supply.

Great little power tank Only used with scope once but worked great. Also used it to power a usb device no problem. The strap just holds on my EQ5 tripod but doesnt hold it on a Nexstar 5SE tripod as its too long but i hung it through the 2 inch holes in the spreader. With the red led on it lit up the area great.

Great powertank This was recommended by Harrisons to use with my new Skywatcher EQ3 PRO SynScan Equatorial Mount & Tripod, and it’s a really nice piece of kit. The built-in lamp is really useful. It does exactly what is expected, though how long a charge will last remains to be seen. Expectations are high! (24/11/2023) Graham - Tywyn
Great price and service. Cheers guys, this works an absolute treat and it's a replacement for the failing battery on my Celestron Evo mount. Thanks also for using Parcel Force and not an cowboy outfit such as Hermes, who are good at losing things! (16/04/2023) Bob Marshall - Wivelsfield Green, East Sussex
CELESTRON LITHIUM POWERTANK Harrison team , thank you for all help, as an amateur. Will be using this kit on my Star discovery mount (12/04/2023) Animesh - Orpington
A great product Fantastic support from Harrison when I was asking questions about the various product options beforehand. And the product itself is a robust and very useful addition to my Celestron telescope. (09/08/2022) -
Does what it says on the tin! An excellent battery pack which also has a built in torch to help when using your telescope outside at night. Quickly charged up & used this for several hours already with my NexStar 6SE. Only quibble -the supplied tripod leg strap is useless. Ultra quick delivery & great price by Harrisons- thanks!

Celestron Lithium power tank Great customer service, despatched and arrived quickly. Unit was excellent, great little power tank. Got 4 hours with a celestron nexstar 5se easily on very little charge. Great value for money. (02/05/2020) Andrew Ballantyne - North of Scotland
Very useful Easy to use, more than adequate battery life, and much preferable to running a cable for a mains operated PSU. The tripod leg mounting needs a little improvisation, but the unit is very good value. Harrison service was excellent (24/02/2020) Kenneth - Dorset
Endless hours of power for your scope! Superb power tank... Charges quickly and last for ages... Defo worth a purchase if you intend of heading into darkness with you scope! (24/01/2020) Andrew - Highlands
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
