The width of the center pin is variable. My one year-old V3 has the widest pin, the five month-old V3 is the most narrow but the new V5 pin is nearly as wide as the oldest V3. I can't see and rhyme or reason for this but that's how it is.This is a shot in the dark, but I was wondering if the width of the positive pin might have something to do with the intermittent "short" problems that a couple of you mentioned.
I had the opportunity to look at a few different variations of the V3 back in January, and took a picture of them from the top. Take a look at the last paragraph and the 3rd picture in this post. You can see that the positive pin inside varies in size. The V3 on the far left is a SI V1.1. while both models on the right are SI V1.5a. Over time it seems that sigelei made the width of the center contact smaller, possibly to reduce the chances of the outer edge of the positive pin from shorting on the threads of certain tanks. You can see that even between the two V1.5a's there is a slight difference in pin width. It's possible that the problem is related to a specific tank's connector when combined with a particular size pin in the Sigelei. It may be way off in left field, but I thought I'd mention it anyway.

Sigelei V5...I'm not Italian but "Forget about it"! It's the best. I will not need another mod ever!
Will I still buy, I'm sure, lol as much, not a chance! I'm so embarrassed to have bought the Provari now!
(Sorry, Provari but you overvalued yourself) I flaunt my Siggy everywhere and people just love him!!! (Looks even sleeker with the SS tank but wish I chrome!)

But I was wondering, what is the lowest voltage it should go to, when stacked, before I change batteries?Welcome welcome welcome to the group!
I'm glad to hear the sigelie is right up there with provari like I thought it was.
Welcome, Freedom. I love your cobalt glass. The only thing missing in your pic is a cobalt blue bottle of juice!Sigelei V5...I'm not Italian but "Forget about it"! It's the best. I will not need another mod ever!

Andria - well take your chosen charge level and x2. I run it to cut off at 6.5 (3.25each) if you want to charge your batteries at 3.4v then you would charge at 6.8v. If you want 3.5v status charge at 7v. Glad you got that kfl working, it's always challenging learning a new device.
I believe with 2 somewhat simple mods the sigelie is right up there in durability with provari. (Board Retainer & new switch) The only difference at that point is the 33hz compared to 800hz pwm. But the +1 the sigelie puts out more power with multiple battery configurations including stacked. One might say with a few mods its the poor mans provari.
Other mods-
Fairmana, so the center pin on the sigelie could be lowered from the inside to allow devices to sit flush. At this point a grinding of the air flow channels would probably be needed if you were using 510 air devices.
I see no inherent vaping problems with the 33.3 Hz Zmax chip used in the Sigelei V3 and V5. I have experienced the "rattlesnake sound" heard when using low resistance cartomizers. To the best of my knowledge the "rattlesnake" is only a sound that emanates from some atomizers used with these devices and it has absolutely no effect on vapor quality.
Overall, the Sigelei V3 and V5 are among the most durable and attractive APVs to be found for less than $100.
How on earth do you guys get the picture big like that?

Jeremy, I'm not sure why you wouldn't consider sealing the underside of the 510 important if you're talking about "durability". I've already seen 2 of these leak through a crack in the 510 plastic and one of them died "permanently" as a result. I can't 100% prove that the one that died was because of e-juice getting on the circuit board, but the probability is very high that it was. I had to clean e-juice off the circuit board, so in my mind it's basically a certainty. Why take a risk that a connector could crack at some future point that results in killing your device? You may never even notice a crack in the plastic pin support until it was too late. It's a 10 minute fix once the device is already apart - well worth the effort and peace of mind in my opinion.
