i have an innokin vtr and it came with a "button top" Efest 2000mAh battery, i also have another battery which is a 2200mAh flat top and both work well in my device.
i do know that my VTR is a secong Generation device so i'm kinda wondering if yours isnt and thats what the newer version addresses
I have the same version 2 with same Efest batteries.
Mine is green. The version 2 does not have the floating 510 connecting ring that spins round when you screw your tanks in or out. This has been replaced fixed 510 connection, as there were quit a few complaints about incorrect resistance readings due to the movement in the 510 ring. the new one is fixed and has 4 air channels instead of 2 on the old design.
Have not seen a complaint about this fault since version 2 came out.
Have not tried any new tanks as yet, just using with the iClear 30s for now, when I get bored I might try the X.1 or Anyvape Davide BDC. Both fit being 19mm.
If I really must try something bigger ill look into removing that retaining ring at the top.
The one shown earlier in this thread looked really good and very neatly done, I doubt I have the skill to do as good a job.
Not going to use adapter I think it loses the whole point of why I liked it so much in the first place.
Tried my protank2 mini and felt like I was about to call in an air-strike.
Anyway I love it so far. Vapes great. Couldn't be happier.
