I unwrapped a 35 amp efest today and it's not a vtc and I'm not sure if it's a lg he2 but I can tell you the numbers on the battery they're 1kb01317 hope that helps end the ******** about them being vtc's anyways
Get I ipv2 it's a small box mod with micro USB charging and from 4 - 50 watts of power and you can build coils down to .2 ohms so it can handle your big dripper no problem 7-50 watts my bad
