This from Mooch. Posted on Reddit. Thanks Mooch for all that you do. As I have said before you just never know what batteries are under rewraps. I've done some preliminary testing and, so far, the news is not good. The newer 20700 performs worse than the original one. See the attached discharge graph. Discharge graph: https://imgur.com/a/wFbtC I'll be doing more testing but it appears to be a 15A-20A cell with a capacity rating of about 2800mAh with a lot of voltage sag. My sincere thanks to James Burr of Evolution Vaping (UK) for bringing this to my attention and for express shipping some to me here in NYC! I also want to thank the others who alerted me too. These new iJoy 20700's are easily spotted since they have four "legs" coming down from the top contact instead of the five in the original cell iJoy used. The ones I received were taken from Captain mod kits but others have said they received them in Genie kits and in orders from IMRBatteries. My recent order from IMRBatteries had the five leg versions of them though.
