One thing you might note is if you get a pkg that is open or missing items reject it immediately. It is tough to prove that it happened somewhere else in the chain. It helps to get to know your mailperson.
I ordered a Blackhawk panzer from fasttech.. Says it fits 18350/18500/18650 yet I can't seem to fit my 18650's in it at all. Is it just a defect or maybe accidently they sent a 26650 mod? Is the 26650 battery longer than the 18650?
26650 is much Fatter. 18650 (18)mm diameter, (65)mm length, (0) Round
26650 is 26mm diameter
Panzer top contact pen screws down to make battery connection. Maximum battery length 70mm so if you have a standard 18650 you need nearly 5mm of screw extension.

Hard to say if that one works like that. There's one with a spring loaded pin. Which is why people should include links to what they're having problems with.
Actually no - the Panzer Black has no locking switch and Spring loaded/thin top cap with no contact issues.
Panzer {BLACKHAWK} is threaded battery adjuster/thick top cap and locking switch. This one is popular for loose battery screw and battery rattle.![]()

I found the screw.. It wasn't even in the mod. It was outside the mod, outside the bag, outside the box, and inside the package it shipped in. How the heck does that happen![]()
And as stated - the Spring loaded pen design has a shorter Cap and NO Battery rattle issues also a narrower mod.
2 of those are NOT BlackHawk and one is Spring loaded and the 18650's fit. I'm not sure where your going with this? I answered his issue.
Performs well too.

Went through the spare parts box today and built a somewhat unique Nemesis Kayfun setup. It weighs less fully loaded than my two other Nemesis setups do without a battery. Have already set it back down or unscrewed the bottom several times thinking it had no battery installed.Performs well too.
From the bottom up it is comprised of:
The switch and tube from this; https://www.fasttech.com/p/1645505
This hybrid connector; https://www.fasttech.com/p/1662400
The base from this (FT sent the entire base as a replacement for a wonky collector tank); https://www.fasttech.com/p/1494700
A clear tank from this assortment; https://www.fasttech.com/p/1662300
The chimney and top cap from this; https://www.fasttech.com/p/1570900
Topping it off is this tip; https://www.fasttech.com/p/1564002
I present the FastTech Frankenemesis KF or perhaps the FTFKF.

Boborone, could it be said the Nemesis has become the small block 350 of the mech mod world? Inexpensive, easy to find, highly adaptable and great performing.
With a stainless, copper and aluminum Nemesis in the stable I have no need for another but each time I see a nice brass atty or tip, can't help but think how it would look on a brass Nemmy.
ENJOY
