Power your telescope anywhere with the PowerTank Lithium LT, Celestron's smallest and lightest lithium-ion power pack.
The Celestron PowerTank Lithium LT is built with Lithium Nickel Manganese Cobalt Oxide [LiNiMnCoO2] or NMC technology, which delivers a steady charge over long periods and requires less maintenance than a traditional sealed lead-acid battery.
Unlike other lithium-ion power packs in this price range, the PowerTank Lithium LT was designed for astronomers by astronomers, specifically for the unique needs of computerised telescopes.
The engineers at Celestron worked hand-in-hand with battery suppliers on PowerTank Lithium LT to ensure that it does not experience this dropoff in performance. The built-in voltage regulator ensures a stable 12V output, regardless of the amount of charge left in the battery. This keeps your telescope’s electronics safe and performing their best, so you can focus on astronomy.
The NMC chemistry used by the PowerTank Lithium LT offers far more advantages than the commonly used Lithium Cobalt Oxide batteries found on the market today. Besides having a longer shelf life and three times the number of charge cycles than LiCoO2 chemistry, our NMC battery offers overcharge and over-discharge protection and can withstand temperatures 100o F (60o C) higher than LiCoO2 batteries making the NMC less likely to experience thermal runaway.
The power pack’s extremely portable form factor means it can go anywhere from a remote dark sky location for astro-imaging to a weekend of camping. When it is powering your telescope, use the included 2" straps to secure the unit to your tripod leg where it is out of the way. Besides the power cable to charge your telescope, no other cables are needed.
If you need to power your telescope and charge electronic devices simultaneously, the PowerTank Lithium LT features two output ports: 1 12V DC port for the telescope and 1 fast-charging 2.1A USB charging port for smartphones and tablets. This USB port can also support any accessories that require 5V USB power.
