hi received my indulgence the other day nice peice of kit also got the 6v option to go with it.i have read on here about normal attys at 6v dont work and it dont work with cartos or 510 but works with 901 if i put my unprotected cr2's in it will vape throughout the range of attys.so its the protected part kicking in on the 16340's my question is.are their any protected 16340 brands out there that will allow 6v on standard attys
