Stable Power Designed for Telescopes
The 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 computerized 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.
You may see competitor batteries claiming that they 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.
Celestron’s telescope engineers 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.
