I have been using these for two days now; drove up to batteryjunction the day I got my SB. I have had NO issues at all.
I have no idea how people keep popping addys, buring carts, etc. I don't think I could pop an addy or burn a cart if I tried with this thing. I would have to do something really stupid. Will post a review soon but I have no idea how so many people have problems vaping at HV. I was ready for a nightmare based on all the posts about HV and after getting a SB and trying HV I am wondering how people mess it up.
Keep your addy wet, if it gets too hot then put it down. Used 3-5 second bursts and you will be fine. It’s really not that hard.
At first I was slightly disappointed with the amount of vapor I get, but then again I expected to be blown off my ... by this thing. I think 6v brings out the flavor in the juice (unlike what other people say) and has just the right amount of vapor; defiantly not TOO MUCH vapor.
I also tried 123a's and did not have problems but they cost too much to just waste in a PV. I think most of these problems with HV vaping are total user error.
Again, unless my SB is broken, I cannot understand all the issues. I wiped off the connectors with alcohol and made sure the spring was tight, which it was. Am I missing something? I do get a little more vapor then my 3.7v protégé and again, the flavor is better but I am not totally blown away or anything. I would say it was just right, which is why I am not complaining, but again expected much more from a HV device. This is my first. I don't really think anything is wrong, just that all the posts here made me think this thing would take master vaping skills not to blow it up and billow unsmokable clouds of vapor but it’s not the case.
In summary, IMO you can use these batteries. For $30 you get a car/wall charger and 4 batteries, which is a great value. I am getting 3.5 hours of moderate vaping out of the exact ones above, but the batteries have not been broken in and expect about 4 hours after the first few charges. The low voltage protection works great and shut the batteries down when the voltage got too low. One minute the thing was working and the next it totally stopped; recharged the batteries and it worked great again. That’s how the protection is supposed to work.
