Hey guys I got a couple fenix flashlights and was wondering if the panasonic 18650 3400mah cells would work in them. The Fenix lights I have are the PD35, TK21, and TK22. I have read some issues with the cells not making contact on certain torches because they do not have a nipple like other batteries. I was also looking to purchase Fenix arb-l2s cells with the fenix are-c2 charger but if I can get something equal or better for less money please let me know.
