Scott_Simpson sir the 200mah aw is 1-2mm longer than the 1600mah ones with the 4 I currently own.

That's interesting because mine are identical. I have 6 of the 1600's and my GF recently got 2 of the 2000's and I can't see a difference no matter how hard I look at them. In fact both fit in my Puresmoker Legacy the exact same and I don't have to change the number of washers in the switch. I wonder if they changed them recently one way or the other?

Really? I didn't know that. Thanks. So, apparently, the convention that the first two digits of a battery designation indicates diameter in mm and the second pair indicates length in mm is just an approximation which varies from manufacturer to manufacturer? I guess that must be true, since I remember reading that some 18xxx batteries are too fat for the end cap on some mods? Anyway, thanks for the correction Morandir!

Frankly I think they all measure them before they put the wrap on them... and on protected ICRs it's w/o the protection board. Protected 14500s are notorious for being extremely long sometimes.

Marck73 sir mine are both the old labeling on two (just the +/- size and mah) and new (made in china, rohs, etc.). The 1600 mah old labels are 18.4mm/64.3mm and 18.4mm/64.8mm, new labels are 18.4mm/65.1mm 18.4mm/64.9mm. 200mah old labels are 18.4mm/65.5mm and 18.4mm/65.4mm, new labels are 18.4mm/65.6mm and 18.4/65.7mm. As I said, very slight diffrence, between 1-2mm.

Any idea where Dave is from?

He's from Sunderland which is at the top end of the country, a few hours away from Scotland.
His accent would be considered "Geordie".

I'm a southerner (London) and there's supposed to be a "divide" between us culturally, although I've never really perceived one.
One thing for sure - our accents are majorly different.

Just had strange issue with my ZMax. Like others have said if you replace the battery quickly none of the settings go back to default. I was switching the battery quickly and the unit fired without me pressing the button and kept firing. The menu still operated but it continued firing. I had to remove the battery to get it to stop. Cannot replicate the issue. From now on I won't try to replace battery quickly and will wait about 30 seconds or longer before putting in the new battery. It is working well again so I hope my PCB is okay. I don't think it was a pressure against the PCB issue with the battery as it was a flat top IMR 18650 1500Mah battery and never had this happen before. I am thinking maybe not enough residual charge left to keep defaults but enough to confuse the PCB when the new battery was inserted. Anyone else have a similar issue to this?

The only regular odd thing I have with the ZMax is when the battery voltage around 3.5 volts or below when I go to the menu it will display at full brightness but after a second or so it gets dimmer and stays dim. It still displays at regular brightness when vaping. I assume this has to do with the low battery voltage so I switch out my battery when it gets to 3.5 volts. I found it gets down to 3.5 to 3.4 volts it will occasionally display "LOU" but still fire. Never had it fully refuse to fire for low battery yet.

2.5volts? did you mean 3.5?
I thought it was to shut off below 3.2v
ok i see you corrected it

I have had this happen. Luckily mine stops after the 10 second cutoff. I have been able to replicate it, but it has only happened with my 18650s and only if I hit the button within 10 seconds of changing the battery. I need to dig out my multimeter and find if it's at a certain charged voltage or something similar.

I don't think I hit the button. i did not wait for the ten second cutoff. I got worried and immediately pulled the battery, waited 30 seconds and put it back in.

Well, something very strange happened a few minutes ago; I left the Z sitting on my desk and went to a short meeting; when I returned, it was smoking and sizzling and had melted the mouthpiece and boiled all the liquid away. The carto was completely burned. Was too hot to even touch without something between my hands. I haven't done anything with it and have no idea if it will even work now. Later today I will install another battery and carto and see if it will fire.

Anyone else had this type of situation with the Zmax?

Well that's freakin' scary as hell. I would return the unit for sure and it gives me pause about mine right now to be honest.

I have an annoying issue. I have an old Smok DC mega carto (the ego type). I can't get it to work on my zmax it just reads 0.9o. It runs fine on an ego batt at 3.2 3.7 or 4.2 (I have an ego booster).

It's a shame because I really liked the massive DC carts and was thinking of going back to them over the vivi novas or DC tanks (which I just find to be messy leaky annoying despite typical good performance).

that means its only .9 omhs and will not work on the z.And if it was supposed to be higher i would trash it before something happens .

Anything below 1.3 ohms will not work onVmax , it puts out F1 and F2 errors on display
Edit: This is how Vmax displays, Zmax is different codes
Edit: With Zmax anything below 1.2 ohms will trigger low load code

I've been having oddities pop up with mine. Nothing as severe as this though. Here's a link to the post I made earlier today describing what's going on with mine.
