Tired of lugging around a heavy battery? Discover the latest in portable power!

Tracer Lithium Polymer (Li-Po) and LiFePO4 (phosphate) Battery Packs offer a tremendous advantage over traditional sealed lead acid (SLA) batteries. Just a ¼ of the weight Tracer 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 Tracer 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.

We offer two ranges of Tracer Battery Packs: Li-Po and LiFePO4 (phosphate):

The LiFePO4 (phosphate) are generally a little bigger and heavier than a LiPo,  but are capable of doing more charge life cycles, boasting 1400+ cycles to the 300+ LiPo offers.
There is also a slight difference in voltage between the 2 types of battery...The LiFePO4 discharge from 13V down to 12V in use, whereas the LiPo batteries discharge from 12V down to 11V.  This is critical for some devices, but not many.
While the new LiFePO4 will last a lot longer and are better designed to power 12V equipment, they are heavier and bigger physically.

We also offer Celestron PowerTanks Lithium, Nevada PS-08 Linear 6-8A Power Supply and more. Please see below.
