Celestron PowerTank Lithium

• The LiFePO4 has an un-recharged shelf life of 10 years compared to 3 years for the Lithium Iron and 6-9 months for a Sealed Lead-Acid battery.
• The battery performance of the PowerTank Lithium phosphate 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 Iron 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-iron designs and will not be a fire danger if accidentally punctured. This combined with its rugged design make it the perfect outdoor power supply.
• Portable power pack for your computerized Celestron telescope using Lithium-Iron Phosphate (LiFePO4) chemistry
• Powers your telescope for up to 10 hours
• 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 and 7 times more than sealed lead-acid designs
• Battery shuts off automatically when insufficient current flow is detected to prevent you from inadvertently draining your battery
