i have an icon myself and just recently picked up a prodigy 3.1. i really enjoy both. im a little lost on the 3 or 6 v vaping from my prodigy ( how it works...how do i vary it? battery sizes?)
This would have been varied by using 2 rcr123 3.0 volt LiFePO4 batteries instead of 1 3.7 volt AW Lithium ICR battery. The stacked battery option is less favored now due to concerns with stacked batteries in a metal tube.
If this option is pursued, please remember:
1. This option is no longer within the recommendations of the manufacter
2. Always check each battery with a multimeter prior to vaping
3. Always check each battery after the initial vape from stacked batteries
4. Only use LiFePO4 or AW IMR batteries with a high enough C rating
5. Only use a 3.0 volt charger NOT a 3.7 volt charger.
6. If in doubt, toss the batteries.
7. Keep your batteries in a pair, don't mix up the pairs
8. Alternate the top/bottem combination of each pair.
9. Use a standard resistance atomizer/cartomizer or higher for high volt vaping.
All of this was too much for me to keep up with, so I switched back to 3.7 vaping. Other options exist now for high volt vaping that don't involve stacked batteries. Puresmoker now has the Legacy with the removable kick from evolv. This too can mimic high voltage vaping. However, YMMV.
