Product Details

  • The PowerTank Lithium Pro is designed for the high-power user! Offering twice the battery capacity of the original, it can handle more demanding applications.

    Optimal Design

    PowerTank Lithium Pro features ports and connections to accommodate a variety of devices. When powering your telescope during observation, use the included 2-inch straps to secure it to your tripod leg where it is out of the way.

    One side features a strip of LED lighting in both bright white and red. This turns it into a convenient safety light during star parties or a work lamp to clean your observing area when the night is done. You can even use it as an emergency light during a power failure to illuminate an entire room of your home.

    Efficient Portability

    The power pack's extremely portable feature means it can go anywhere! From a remote dark sky location for astro-imaging to a weekend of camping with no power plugs, the PowerTank Lithium Pro is a great accessory to bring along! PowerTank Lithium Pro can also travel with you on your next vacation! At 158.74W-hours, it 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.

    Longer Shelf Life with Celestron’s LiFePO4 Battery Chemistry

    PowerTank Lithium Pro's LiFePO4 chemistry holds up to 2000 charge cycles and has a shelf life of up to 10 years!

    You won’t have to remember to recharge your battery every few months like you do with a sealed lead-acid battery. Its long, 17-hour capacity and lack of maintenance make the PowerTank Lithium Pro the ideal choice for an emergency kit. Store one in your home, your garage, and even in your office!

    PowerTank Lithium Pro is smaller, lighter, and safer than sealed lead-acid batteries. This technology is also more environmentally-friendly since it does not use toxic heavy metals.
