I understand that for some people, seeing is believing. I will do my best to try to help bring you into the light:
This picture below shows an original auto VK battery on the right and a newer manual VK battery on the left.
I am sorry for jumping in on this subforum with a "negative" attitude, and it's not that I have any bad words for V4L product or staff...it is a good product. I just can't tolerate misinformation...people do not realize how statements stick to people seeking info...no matter if its fact or not....
I am not going to go back and forth....DO the research PLEASE
The slot is no longer there on the new manual batteries
not kr808d-1 model and I am pretty sure that the new auto batteries that Steve is waiting on has the exact same design as the manual batteries on the left
no slot on kr808D type batteries not a new thing. Though I do not have any other KR808D-1 batteries to compare against, I am willing to bet that every single one of the generic KR808D-1 batteries on the market have the slot like the VK battery on the right
That is most likely true unless older no slot ones available.
How does it make the VK better you ask? The lack of the slot results in a slightly decreased airflow, which in turn results in a draw that is more like an analog with much better vapor production
does that mean slotted batts have less vapor than no slots and if so what about the vapor claims of the auto batts before about vapor production..
So what does it all mean? It means that Steve and the Crew over at V4L are working very hard to make sure that their product is the best it possibly can be. Hell, they already have everyone else on the planet beat when it comes to customer service.
As far as the cutoff. All of the batteries currently have a cutoff, but the manual PT does not. Steve has actually said himself that he is working on getting the cutoff eliminated on all of the batteries because "anyone should be able to take as long of a drag as they want" or something to that extent. Steve actually said something like that in a previous post, I'm just too lazy to dig for it
