Just got these from an Ebay seller, but not sure what to make of them. They seem legit, but I'm not very experience with telling the difference. They throw 20A fine, I've only been able to test them on a .2 Ohm coil so far. IMG_20150123_031543.jpg

I've noticed the most consistent thing is the dual rings. All fakes seem to have only one ring.

It's actually not dual vs single rings...the real ones have two rings but the space between the rings is very small on the real ones. The fakes are likely rewrapped Samsung 25R cells.

OK thanks for the advice, but a couple days ago I ordered these after reading the guy's feedback. Anyone vouch for this seller?http://pages.ebay.com/link/?nav=item.view&id=251787216291&alt=web

After looking at your picture and my VTC5's, I'm convinced yours are fake because of the wrapper seam and the casing at the top.

I know of no authentic VTC5's on the market right now. I strongly suspect when they do show up again it will not be on Ebay, but from a known large supplier. If you really need to 30A rating, I would buy VTC4's from Illumination Supply. They are legit.

And that wouldn't be so bad considering 25R are very good batteries and really should not vent with flame or explode if abused. The problem is people who wrap with fake wrappers do not have to use 25R's. Basically, you just don't know what you've got and that would make me very reluctant to vape them in anything, but specially in a mech mod :)

That's why I'm considering picking up an analyzing charger like the Opus BT-C3400 so I can see what the actual mah and internal resistance of the battery is. That should give some clue regarding what you might have in hand.

I got an Opus (the newest rendition, the v2.1) a couple of weeks ago. While I think it's great, the internal resistance reading is a bit iffy. The same battery can read very differently in different slots, and in different tests in the same slot even. You also need to detract the resistance of the connection (which I believe the manual states is 30 ma). I think the internal resistance is simply to small in the batteries we use to get a truly reliable reading without a really solid connection (which is not possible with the spring loaded slots). Nonetheless, I would certainly recommend the Opus for its other functions.

I got these VTC5 on ebay last year july... are these fake or authentic?
based on this site, How to spot a fake Sony VTC5 battery
my batteries seem to be authentic, no?

I have VTC5 and Samsung 25R. The grooves on the outside diameter of your battery, just under the positive end, look exactly like the ones on my 25R and not like my VTC5s. Great 20 amp batts if that's what they are.

The best way to make sure you get authentic batteries is to use known, good suppliers that don't sell counterfeits. The following are as best I can tell good:

Illumination Supply
RTD Vapor
Lighthound
Orbtronic
Battery Junction

Illumination Supply generally have the best prices on batts of any supplier I've seen, even the ones selling counterfeits :)
