I would like to preface this by saying I absolutely do not encourage anyone to vape like I do---now ... I own both versions of the xxx mod and have been using these batteries(ijoy20700) and they tear up( become permanently weak ) very fast compared to the 18650s I use. I run .05-.08 and take around 6-10 pulls before charging as to not allow the battery to get hot..they lasted about a week and a half compared to about two months for the 18650( aspire 1800, lg hb6) . Also the thermal coupling tends to become damaged instantly on a few Ive gotten .. then they don't fire at all without going straight to red hot... just putting some real life info to the discussion.. have tried one Sanyo 20700a and it hits harder and hasn't stopped for the month Ive had it ... this might be useful to those who vape mechs this way ( more vape this way than most realize).. looking forward to the big three making a more quality product
Hmm...I've subjected the iJoy's to some pretty serious abuse without problems, about 15 cycles, but I'll try to do some longer abusive cycle life testing soon.
