Designed for astronomers by astronomers

Power your telescope anywhere with the PowerTank Lithium LT from Celestron, their smallest and lightest lithium-ion power pack. This handy device is a must-have for your telescope and accessories, camping gear, emergency kit and more. The PowerTank Lithium LT is built with Lithium Nickel Manganese Cobalt Oxide 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.

Telescope electronics are very sensitive to voltage. Powering a telescope with lower-than-optimal voltage can cause the motors to strain with heavier loads and can even cause the electronics to glitch. The PowerTank Lithium LT uses a built-in voltage regulator to ensure that it delivers at least 11.8 volts for most of the life of the battery, until the battery is depleted and shuts off. Other battery manufacturers may claim that their products hold enough watt-hours of electricity to power your telescope for hours. The technology in these batteries was originally developed to power much lower-voltage electronics, such as home CPAP machines. Although the voltage actually being delivered starts off at 12V, it diminishes rapidly, impacting your telescope’s performance and becoming functionally useless within about 2-3 hours but Celestron’s telescope engineers worked hand-in-hand with battery suppliers on PowerTank Lithium LT to ensure that it does not experience this drop off 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.

Compared to a lead-acid battery, the PowerTank Lithium LT is smaller, lighter, more efficient and better for the environment. It offers better performance, a longer lifespan and safer operation than other low-cost lithium-ion battery chemistries. It also offers automatic shut-off, reverse polarity protection, charging/discharging protection, overcurrent protection and short circuit protection.

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.

The power pack’s extremely portable form factor means it can go anywhere from a remote dark sky location for astroimaging to a weekend of camping. When it’s 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 and it also meets current FAA carry-on baggage regulations, so a perfect accessory for your travels.
