I hate waiting for shipping. Hopefully you get your stuff soon. Now that I have finally gotten my NCR18650A's I've been doing all sorts of testing on them. After some initial issues with the Solo because of polarity and the lack of a standard for the wiring direction of RCY plugs I built a pack and started testing it. I am very impressed by the capacity and quality of these cells. I just finished a session with the new battery pack, and the Solo's battery indicator is still showing 7 when I turn it on. My old pack would have been taken down to 5 by just one session. Heat up time seems to be slightly better as well but I've yet to time it. I also put on of the new cells into my Inhalater and there is certainly a tangible decrease in heat time and increase in battery life. Not as much as the Solo, but still very noticeable. Inhalater uses 2800mah cells in their vaporizer so it is not as much of an increase in capacity over the old cell. Here's some ugly prototypes for those of you who like the gut-shots. Don't worry, the "production" packs are going to be much prettier.
