was away from the comp for awhile. well Karl it was free, which is a real shame. Got a free sample from Ti with free shipping they were very generous.
Currynoah, they are 18650 2600mah from a shop in Funan selling torchlights and fake weapons. They were 18 apiece. Got a pair of trustfire 18650 w the fire pic for Rm60. Both were working wonderfully with no lag after 2 days of use. The unit performs very well w no apparent lag of power; it is putting out constant voltage set. But like you guys know I have been searching hi n lo for something like this. The idea of vaping with no worries for 2 days and that u can charge with something u can get locally with replaceable batts makes me a happy vaper.
