Power your telescope anywhere with the PowerTank Lithium LT, our smallest and lightest lithium-ion battery pack. This handy device is a must-have for your telescope and accessories, camping gear, emergency kit and more.
Stable performance for telescopes
The PowerTank Lithium LT uses lithium nickel manganese cobalt oxide [LiNiMnCoO2] technology, also known as NMC technology, which delivers consistent power over long periods of time and requires less maintenance than a traditional sealed lead acid battery.
Unlike other lithium-ion power supplies in this price range, the PowerTank Lithium LT was developed by astronomers for astronomers - specifically for the special requirements of computer-based telescopes.
Modern telescope electronics react very sensitively to incorrect voltage. Running a telescope at too low a voltage can cause the motors to suffer at higher loads and the electronics can even fail. The PowerTank Lithium LT uses a built-in voltage regulator to ensure that it delivers at least 11.8 volts the entire time until the battery runs low and shuts down.
There are batteries from other vendors that claim to contain enough watt-hours of electricity to power your telescope for hours. However, the technology in these batteries was originally developed to power much lower voltage electronics, such as home CPAP respirators. Although the actual voltage output starts at 12V, it decreases rapidly, affecting the performance of your telescope and becoming useless within approximately 2-3 hours.
Celestron`s telescope engineers worked hand-in-hand with battery suppliers on PowerTank Lithium LT to ensure this loss of performance does not occur. The built-in voltage regulator ensures a stable 12V output voltage regardless of the amount of charge remaining in the battery. This keeps your telescope`s electronics safe and powerful, so you can concentrate on astronomy.
The NMC technology used by the PowerTank Lithium LT offers far more advantages than the commonly used lithium cobalt oxide storage units available on the market today. Our NMC battery not only has a longer shelf life and three times as many charge cycles as LiCoO2 storage cells, but also offers overcharge and over-discharge protection and can withstand temperatures 60?C higher than LiCoO2 batteries, reducing the likelihood thermal overheating of the NMC cells is lower.
Compared to a classic lead battery, the PowerTank Lithium LT is smaller, lighter, more efficient and better for the environment. It offers better performance, longer life and safer operation than other, cheaper lithium-ion batteries. It also offers automatic shutdown, reverse polarity protection and charge/discharge protection as well as over-voltage and short-circuit protection.
Use in the field
The extremely portable body allows you to take the battery pack anywhere, from remote, dark-sky locations for astrophotography to a camping weekend. You can attach it to your telescope using the included 2" straps on the tripod leg, where it won`t get in the way. Apart from the power cable to charge your telescope, no other cables are required.
The PowerTank Lithium LT has connections for a variety of devices. There are two output ports: a 12V DC port for the telescope and a fast-charging 2.1A USB charging port for smartphones and tablets. This USB port also works with accessories that require 5V via USB.
Traveling with the PowerTank
The PowerTank Lithium LT can also accompany you on your next vacation. With 73.3 Wh, it meets the current FAA and EASA regulations (160 Wh and 100 Wh, respectively) for transport in hand luggage. Please check with your airline in advance to ensure they do not have stricter policies.
