As more of these units migrate into owner's hands I thought it might be a good idea to set up this thread. Purpose is to share actual ownership experiences and help each other get the most out of our vmax. Please share your setups here...what works well, what doesn't, problems encountered, etc. My take? It has worked very well for me thus far but I've only owned it for about a week. Tips: The Smoktech DCT's almost appear specifically designed for the vmax. The fit, dimensions and overall look of the new 4.0ml and 6ml DCT's are excellent to my eyes and promote a simple, functional elegance. These tanks have also worked quite well for me overall with the 2.5ohm ST DC cartos, with the excetpion of the occasional flooding episode, particularly on the larger tank for some reason. I'm usually vaping, depending on the juice, between 4-4.5v on these tanks/cartos. Quirks: We all know by now it hits harder at the lower voltages so adjustments are necessary. I recall reading somewhere that the unit is apparently designed to simply stop working with no warning when batteries drop to a combined low of 6v. In contrast, and according to my my experience, once it drops below 6.5v, a 'Lo' warning starts flashing on the LED during use. I took the batteries out for recharging when the vmax registered 6.4v and flashed this 'Lo' indicater. However, the batteries actually measured out at 3.51v each. So there appears to exist quite a discrepancy between the the vmax's battery measurement and what my multimeter reads.
