batteries die really fast

[umzungu]

Hi,

I am running a kayfun light on a atmizoo roller. Coil measures at around 1.9 ohm.
an 18350 battery is suddenly lasting only an hour or two.

Is there something wrong with my coil?

Help appreciated.

Built a new coil, same problem!! This is driving me nuts! Battery lasts about an hour!
Two diff mods, 4 diff batteries, never had a problem before???

Bad/old battery?

4 2 month old AW IMR 18350's in rotation. 2 diff mechs, 2 diff attys.
Think I may have found the problem - realised charger was only thing in common here, it appears the switch on the side got accidentally switched from 3.6V to 3.0V. Am charging batteries now to see if this is the issue. I hope so - am going crazy here!!!!

Yup that will do it!

At the 3.0V setting batts come off at 3.6V which is when we normally place them on the charger. At the 3.6V setting batteries charge to 4.2V

seems to be resolved - was going totally crazy? thought somehow I had managed to kill 4 batteries!!

I kept reminding myself to put a piece of tape over the switch on mine, but this thread led me to finally do it!
