Tracer Battery Packs

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.

Lighter. Smaller. Better.
Just ¼ of the weight of a traditional sealed lead acid batteries. Tracer Li-Po and LiFePO4 (phosphate) Battery Packs will easily fit in a coat pocket or clip to your belt. Gone are the days of carrying heavy lead-acid batteries. You won't believe the difference!

Flat Discharge - Brighter for longer
Li-Po and LiFePO4 (phosphate) technology gives a very flat discharge curve which means sustained power to the end of the cycle. If you are powering lights they will remain brighter for longer, giving you sustained performance.

Built in Fuel Gauge
With the built in Tracer fuel gauge you can check the power level remaining in the battery. A touch of the button shows how much energy remains and whether you need to recharge.

High Efficiency Smart Charger
Li-Po: The compact 1.6A Smart Charger (included) will charge your battery quickly.
LiFePO4: The compact 4A Charger (TR8205 included) will charge your battery quickly.

The battery pack is protected against over charge and discharge, there is also short circuit protection.

Certified Safe
All Tracer Li-Po and LiFePO4 Batteries conform to standard UN 38.3 which is the ONLY relevant safety standard for lithium batteries. Our battery packs have been through a rigorous testing procedure by UN certified inspectors. You should NEVER handle a non-certified lithium battery pack.
