Product Description
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 Included
The 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 Lasting
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.
Further details
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.
