You're right Houdini...I think I'll up it to 6v. You would think the chuck would hit as good as the riva a lot longer though, with the 3000mah battery. I swear that riva feels like a fresh battery for hours, and I'm feeling like my ultrafire 18650 is good for about an hour or 2 before I'm not getting much
vape. Although it'll
vape like that a long time, it's just not as satisfying. I realize it's not the chuck, but the battery, but I am going to try a couple of 3v batts, and see how that does. Will my 510 attys be alright with that, or do I need to get a hv atty?
Oh, I see in your post, that I do need an hv atty. I'll order some of those also.
