Highlights

  • 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
  • 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
  • Battery shuts off automatically when insufficient current flow is detected to prevent you from inadvertently draining your battery

The PowerTank Lithium keeps the charge going for the astronomer on the go. The Lithium-Iron 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 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.

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.

Q:

PowerTank Lithium – Auto Shutoff Feature

A:

PowerTank Lithium batteries come with a safety feature that prevents them from slowly discharging if they are left unattended for long periods of time.

This feature works by monitoring the current being drawn from the battery. If the current drops below a threshold level, the battery automatically turns itself off.

  • For PowerTank Lithium batteries that use a 12V telescope port, the threshold is 250mA.
  • For PowerTank Lithium batteries that use a car battery adapter port, the threshold is 420mA.

Celestron computerized telescopes draw more than 250mA when the mounts are powered on, aligned, and tracking. However, if you turn on the battery and telescope, but do not align and engage the telescope's tracking motors, your setup may not draw enough current. After a prolonged period, this could cause the PowerTank Lithium to turn itself off.

When using a PowerTank Lithium Pro battery to power your computerized telescope, we highly recommend using the 12V telescope output to provide power to your mount. The car battery port was designed to provide power for much heavier loads (up to 10 Amps). To accommodate this larger load, the threshold for the port was increased to 420mA. Some Celestron telescopes, even aligned and with the tracking motors on, may not draw 420mA of current. This could cause the battery to turn itself off. You can avoid this by using the 12V telescope port.
