I do not have mine yet but these are run on a cnc so they are all exactly the same. What is wrong eith the measurements from the site?

Nothing to the best of my knowledge. Mistakes do happen, and buying without one in hand along with a caliper -- well call me ..... :) Trying to decide between the P18 and P16.

There is a thread from a couple weeks ago that David posted the dimensions as 20mmx104mm so I am quite sure that this is the right measurement. If you search P16 dimensions the thread states dimensions for the p16 and on the second page he says the dimensions for the p18.


Thank you ata.

To be more clear after some thought:

I was in know way impugning David's ability nor integrity.

Dimensions on a site do not particularly reflect the true dimensions.
David could have posted those dimensions as accurate for a layman.

They may indeed be accurate W/I +- .0005, he seems the type.

Just as an add on-- Nothing to do with David here: cnc machinery is not necessarily more accurate per se than manual machinery. That's a function of numerous variables such as programming, tooling, and the human element. As a general statement it's certainly true that cnc is more accurate for higher volume runs with all variables at their highest potential capabilities.

I'm sure David does a final inspection to stringent tolerances for all his products . My question was geared towards the terms of the site dimensions.

I don't think that anyone would take it as you putting David down, at least I didn,t and you may be right, it might be rounded down or up to the nearest mm. But I figure that is good enough to have a good idea of the size but I am sure someone that has already received theirs will measure it for you. Not trying to argue or anything but I always thought once a program was written for a cnc, that it would run exactly the same thing every time. Is that the way it works or no? Otherwise why would it be the Precise?:laugh:

Since I don't have a P18, I measured my P16 and two P10. (Tossed in my two S6s, just for the hell of it.)

P16 diameter is 18.41mm, in the larger diameter areas and 18.15 where it steps down in the center section of the device. The site calls for 18.5.

P10 #1 is 12.18mm and 11.91. (The site calls for 12)
P10 #2 is exactly the same as #1.

S6 #1 is 17.43mm and 16.99
S6 #2 is 17.38 and 16.88 (This was one of Davids first all aluminum S6s and I have probably removed at least that much on my buffing wheel.)

I only reported the diameters since the LOA is dependent on measurement process. (To end of ears, end of button, etc.)
Measurements were taken with a caliper as it was the most accurate tool I have at home. (If you need measurements with extended discrimination, I could take them to work and supply data to .XXXXmm along with out of round, max dia, min dia, etc.)

With all that said, I simply can't see where there is enough difference to worry over.

I have owned most of the mods available and found none close to the quality of the Super-T offerings.

Best of luck on your decision.

Lol, Mike
Just wait until I really have a little time.
Could be fun to record diameter measurements at .010" increments along the entire circumference of each device. I could then run a statistal analysis data sheet of the process variation within one device as well as comps to my other Super-Ts.

Then again - I could just enjoy the exceptional craftsmanship, David provides, and find better use for my time. LOL

See you at the next Vapors meeting.

I wasn't trying to argue either, you'll have plenty of that after your big day:D

Seems like things are a bit blurry today, oh lemme see. Is VM offering to send me a P16? Oh my, so generous.:laugh:

Thanks for taking the time. It seems the site dims are solid.

Your post implies you work within a manufacturing environment. You own a bunch of Super- T products. This gives me further confidence whatever my decision.

Sure, if someone sends me 2 spare P16s, i'll be happy to send you 1 :laugh:

I'm away for 12hrs a day min. so I'm leaning towards the 18.

Being away for 12 hours, w/o access to a charger, I'd want to carry 2 spare fully charged 16340s in addition to one in the P16. One spare would be absolutely needed, the other would be for extra peace of mind that I'd be well covered for the duration. I would probably utilize all three in that timespan. (1650mah total)

I haven't used an 18650, but i suspect 1 would be more than enough for 12 hours w/o backups on hand. (2600mah)

So an extra batts or larger device tradeoff (plus the HV option with the P18 is a perk).

Sounds like the P18 may the better choice for you. Either way, you can't go wrong, these MODs are top notch.

True! But 6V is 6V :banana: and IMRs all the way baby for LRs

true. 6v is another story vs a LR 510 or even vs 5v.
I just want a very small battery that performs very well.
We're all just too needy here. anyway...back to the thread..

honestly, with the P18 you can't go wrong b/c u have a HV AND 3.7v option.
some people can't make up their mind and switch back and forth between HV and 3.7. =)
