I have a post here, I think on the second page and in the thag built forum on my learning curves with six volts. I use the 3.2 and do just fine with the map. Couple things to be careful though, use a pair of batts that have a few hours on them already before breaking in your new 3.2. Replace just one batt then alternate. I did that for a day or so then I was okay with using batts right out of the charger. Don't hit the button a long time, shorter hits and more time between each one. The chain vaping doesn't work so well. You need to give it a rest before you hit the button each time. Once you get a feel for the tipping of the tank and the length of button time, it is all good!
