Good morning everyone,I have an issue with the mod that has got me stumped at the moment.This might get lengthy to explain it,so please be patient with me.O.k.,the kit itself came with 2 3.0 ohm atty's,and 1 free carto(not sure of the cartos res. it was free).The first atty i used and started dripping for the first day,no problem at all,everythings fine.Go to bed and i took battery (2 18650 high drain batts not stacked) out and atty off,put everything in case.Next about 1-2 o'clock,grab for mod for a vape and put batt in,and atty on start dripping.About 1 hour later take a hit and nothing(got a reading of 9.9A,and a LO code on mod),unit is on and working nothing from atty.Put the second fresh atty on,nothing.So i took the first one that started working and grab my ego pop it on and it works fine.Second one,pop it on ego and it works too.Now go back to mod,nothing.I then took the free unused carto out and put it on mod it works???Again i try the atty's,nothing again,but they still do on ego???? I have 3 rba's i want to use on this mod but at this point i am not sure they will work either?? I am still waiting on tim to get back to me.The rba's work on the ego fine but i want to kick them up a little using the mod.Any advise,help,most appreciated.
