The Celestron PowerTank Lithium is a lithium-ion battery designed to provide reliable, lightweight and safe power for astronomical telescopes and portable electronic devices. Thanks to its extremely compact size and low weight, it is an ideal solution for demanding astronomers who require high autonomy with minimal bulk.
Portable Design with Direct Tripod Mounting
The included hook-and-loop mounting strap allows the battery to be attached directly to almost any tripod. This eliminates cable clutter and keeps the observing setup clean and organized. The design is optimized for mobile and portable observing configurations.
Fast Charging and Long Operating Time
