I think you will be happy with it. The
tank isn't my favorite though. I use a Melo2 on the iJust2 battery and a 0.3 Kanthal coil.
On a regulated box mod (eleaf TC60W) I run the Melo2 and 0.3 coil at 52 watts. I have no idea of course what the output of the iJust2 battery is, but it is quite comparable regards draw and performance that I find on the regulated box mod. Not only that, but the iJust2 battery has long life and the performance is consistent throughout the duration of the charge. So while it is technically a mechanical mod ... it seems in some way regulated.
I know the iJust2 battery has an onboard PCB but other than provided safety features, I have no idea if there are any performance features. I tried a 1.8 ohm coil in a
tank on the iJust2 battery and it did sputter/pop just a bit while performing satisfactorily. I was able to tame that somewhat by use of the
tanks air control.
