This is a good reason to get a provari i would suspect, since it has its 'accuset' technology, but can it handle the LR stuff due to amp limiting etc etc? im still pretty new to VV as all my prior
devices have been mechanical
mods (mainly GG).
3,5A is not easy to hit. So yes, you can use any stock made LR atty.
I never owned a Vmax, and don't plan to since I don't want to use 2
batteries (not because they are stacked, but because it makes me own twice the amount of batteries and make the device bigger; I use PV Mini), so I won't comment on its performance.
What personally bothers me with it is that people seem to report it "hitting hard" on lowest settings. Oftentimes I do dial the voltage DOWN, be it for setting up the coil and testing something, be it because my throat hurts and whatnot. I don't see how having a low setting hitting hard could be a good thing. If I want low, give me low.
The only limitation I hit with ProVari was self built parallel coil on a genesis atty, that I couldn't get above 4,8V. I don't recall exactly what was it final resistance, but I didn't vape it long either, as that kind of setup kills my small 18350 battery super fast.
