What is Bulk Rate? BulkRate is a semi-wholesale system with items priced separately from retail. When you use bulk rates, a flat $1.70 registered air mail fee will automatically be added to your cart to ensure delivery of package. While BulkRate's intention is to offer cheaper prices when you buy in bulk, because it is priced separately it on occassions show a higher than retail price. That's why we ask you to enter BULKRATE as a coupon code to manually activate the rates. You can always opt not to use the bulk rates. If you are looking for wholesale prices please feel free to contact us.

Pros: Hello everyone!
I just recently found about CREE Flashlights, so am not really a rookie just a beginner.
I bought few models of DX and all modells are power either with CR123A or 18650 Lithium Batteries.
My flashlight beam is as shiny and light as i wish. I was once a fan of Xeon lights like maglite and stuff... my pro gear now is a SSC lamp powered with one 18650 cell!
maybe these protected cells could be usefull for remote controlled devices as well?
 
Cons: I can really say cons here but here a few
-not really 2400 mah
I need to test them how many charge and discharge cyles these battiers hold... this may take a while
 
Other Thoughts: I just bought 40 packs of these for my friends and customers. real bargain here!
 
Bottomline: If you need 18650 cells buy there, u wont regret it!

Pros: I was pleasantly surprised to find that this fit the Jet III Pro, which apparently has a reputation for only just fitting other cells.  I went out of my way to order a certain premium brand of 18650s as well, but discovered that these ones fit anyway.
 
Cons: None that I've noticed so far.
 
Other Thoughts: Nothing to report.
 
Bottomline: They're batteries, they're protected, and they do the job.  You do tend to get what you pay for, though, so I won't be suprised if these don't last as long as the cells I paid more than twice as much for.  Really, how far wrong could you go with these?
