FEATURES

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 7.2 Ah 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.

LiFePO4

Sunday, 24 June 2018 | Steven

I wanted a small compact power supply to drive duel motors on a Vixen GP and after looking around at the various options and asking advice unsettled on the LiFePO4.. It's compact and certainly more modern looking than the powertank options and can easily, with the supplied strap, be fixed to a tripod leg so its out of the way. Operationally the controls are accessed through a flap on the top of the battery. Here you can access the power check/power on button and the light on/of button as well as the two USB ports (1.5 & 5v).

Charging the battery is easy, the accessories supplied in Clyde numerous socket adapters and you simple plug the charge cable in to the power port on the battery.. a secuence of lights illuminate for 25%, 50%, 75% & 100% charged.

I have found two issues with otherwise a good product. Firstly the USB's don't work/charge when the battery is running a scope, why I don't know but I would have thought that would be just such a useful option. Second issue is the "lid" to access the controls was not very flexible and after an attempt tonality it to plug in a USB i actually broke the rubber strap holding the lid to the battery.. just a bit too rough with it i guess, but it should have been easier to access too.

I actually carry the battery in the car for powering kids toys/loads and other charging requirements. It also makes a great light, white or red for home, loft or work..

4 stars because of the two issues above, but otherwise happy with product, better than 8D type batteries every few weeks!

Handy

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.
