The Infinite version I see on Ebay from CodeVape advertises the 3 fixed pins, not a floating.
Infinite revised their Caravela. Their first version had 3 separate pins like the original. The revision has not a floating pin, but a copper telescopic pin (a better solution anyways). If you can find a newer version, you're likely better off with that one. No pins to keep track of, and copper contacts.
Whether they fixed the threading flaw where the serial number doesn't align with the Caravela logo is another question.
The Infinite Caravela does NOT have the Pedro signature (which is a good thing IMO).
I have the Hcigar version, and I've found that "some" batteries fit properly, but it's dependent from battery to battery (even those of the same brand). It works fine and looks great, but I'm not sure I would buy it again. I'd look around for the newer Infinite version.
