Product description

The 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.

I use this battery to power my Nexdome rotator system. It has been perfect for the job, no problems and runs all night. I have checked the power usage and it maintains a consistent supply. It may appear expensive but you will buy two three or four batteries with other technology before this one dies plus you don't have to worry about totally draining the battery and ruining it as you can with other technologies. Yes the flap comes off, no big deal if necessary you can still use it.

An expensive USB hub

Power cuts off randomly, ruining my alignment and i have to start again. If i just leave my mount tracking it will work forever but as soon as the mount reverses direction like during GO-TO or the initial alignment the power shuts down. Also the 2 USB ports cannot be used at the same time as the 12V DC output, it can only supply power to one port at a time. The flip-up dust cover permanently came off (some plastic bits broke) after my second time using this.

Never buy this product, it does practically nothing its supposed to.
