Well ..... More than battery life. If you truly want to go above 80 watts, that's about the upper limit for 1 battery mods. And then only using the higher amp/lower mah batteries. Also need to be aware of some mods limits, for instance Cuboid, & I believe VTC mini have a 25 amp limit. This doesn't affect 'most' users, but some sub-ohm'ers running hi wattage.
For most part, selecting a mod is the easy side .... There's a huge selection of great mods available, boils down to what your needs are & looks. Attys on the other hand is a much tougher call, & theres great ones popping every month!
