I don’t know about the Tool AA V2.0, but the 1st version hanged the 14500 well, except for the heat! It is too thin, the pill is aluminium and so it gets hot very easily.
To nick, if you mod, I would suggest modding a flashlight like the Convoy T2, the Jaxman E3 or the Sofirn SF14! All easily moddable and all take 17mm drivers!
