The Celestron PowerTank Lithium Pro is a higher capacity battery unit for astronomers and photographers with high power needs.  PowerTank Lithium Pro offers twice the battery capacity of the original, making it ideal for more demanding applications.  The PowerTank Lithium Pro features a variety of ports and connections to accommodate your devices. A 12V DC 5A telescope power port (Celestron cable included), a 12V DC 10A car battery adapter port, and two 5V DC USB ports - one 2.1 A and one that supports rapid charging.  The Powertank Lithium Pro makes a great back up battery for camping as well, with enough power to charge up your phones, cameras, tracking devices, headlamps and more. A compact form factor of 8.75" x 6" x 4" deep, it weighs just 4.5 pounds making it an easy choice for backup power no matter where you're going. The compact LiFePO4 battery features 2" straps, allowing you to secure it to the leg of your telescope tripod or anywhere convenient.

The Celestron PowerTank Lithium Pro also doubles as a safety light with a strip of bright white and red LED lights on along the side of the unit.  The red light serves as night vision safe lighting for nighttime use making setup and cleanup easy in the field and keeping feet away from tripod legs.  The bright white LED can easily illuminate an entire room during a power outage or light up your car for roadside repairs.

The Celestron PowerTank Lithium Pro is also travel friendly!  At 158.74 Wh, this compact LiFePO4 battery meets current FAA regulations (160Wh) from transportation in your carry-on baggage.  Please check in advance with your airline to verify they do not have stricter policies.

Advantages of Celestron’s Compact LiFePO4 Battery

Powered by Celestron's Lithium Iron Phosphate (LiFePO4) battery, PowerTank Lithium Pro is smaller, lighter, and safer than sealed lead acid batteries. The technology is also more environmentally-friendly since it does not use toxic heavy metals.

PowerTank Lithium Pro’s LiFePO4 chemistry holds up to 2000 charge cycles and has an un-recharged shelf life up to 10 years. That means you won’t have to remember to recharge your battery every few months like with a sealed lead acid battery. Its large, 17-hour capacity and lack of maintenance make the Telescope PowerTank Lithium Pro the ideal choice for an emergency kit.
