About this product

Portable Lithium PowerTank for your computerized Celestron telescope.

  • New lithium iron phosphate (LiFePO4) chemistry
  • 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 & 7 times more than sealed lead-acid designs
  • Un-recharged shelf life of up to 10 years
  • Environmentallyfriendly - Does not use toxic heavy metals

Employing a more environmentally-friendly battery chemistry than previous iterations Celestron's Portable PowerTank Lithium 84.4Power Supplygives you the power required to run your motorized mount with the added capability of charging small electronics such as smartphones, tablets, and cameras.

An integrated white LED flashlight, with two output settings, gives you the illumination you need to get to your observation point and set, and a separate red LED light allows you to perform tasks like swapping eyepieces or attaching filters without affecting your night-adjusted vision.

This PowerTank has a compact form factor at 19cm x 7.5cm and weighs in at just 1kg. Two straps are included so you can either hang it or attach it to the tripod, but if you want to leave it on the ground it has an IP65-rating making it dustproof and water-resistant.
