These are 18650 flat top li-ion batteries. They are labeled as having up to 3600mah, but like most 18650 cells on the market, we have found that to be inaccurate. Grade testing in our XTAR shows these are your typical 2200-2500mah cells, which are perfectly fine for powering sabers.
These are used in all EFX sabers. Please check that your saber uses 18650 cells. Some of our Proffie powered sabers use 21700 cells, not 18650.
We want you to be able to rock on with your saber, so we have priced these cells pretty low and priced the shipping really low, too.
High rate discharge with no memory effect
Protected against short circuit, over charge and over discharge
Actual batteries you receive may have a different color wrapper from the picture. Most are blue, but some are white, black, and even purple.
