Power Supplies

Lithium Polymer (Li-Po) and LiFePO4 Battery Packs offer a tremendous advantage over traditional sealed lead acid (SLA) batteries. Just a ¼ of the weight our battery packs will fit in your coat pocket with room to spare! You won't believe the difference! Built-in charge indicator shows how much power remains in your battery and whether you need to recharge.

Not only you can use Battery Backs for powering your Astronomy Equipment but also for  Portable Lighting Solutions, Point of Sale displays, Mobile Advertising, Covert Surveillance, Remote Monitoring Equipment, Outside Broadcast Solutions, iPhone charging, Portable TV/DVD players, and many other 12V applications.

Celestron and Sky-Watcher Power Tanks is a portable budget solution to power your telescope. Power Tanks are lead acid batteries and their charge needs to be kept topped up. It is important to recharge your PowerTank after each period of use. Allowing the battery to discharge power over several periods of use, and not re-charging regularly can lead to the condition where the battery can not be charged with the supplied charger.
