Product Description

Style:PowerTank Lithium 84.4Wh Capacity The new PowerTank Lithium keeps the
charge going for the astronomer on the go. 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. Keep your telescopes, smartphones, tablets, GPS
systems, cameras and other USB-powered devices as active as you are with
PowerTank Lithium—the ideal outdoor portable-charging solution for your
electronic gear.
