Two completely different things. the 20A limit of the 25R made it reliable for most regulated mods, while the Sony VTC 5A are the norm for mech mods because of the 30A limit. Regardless of the capacity, since VTC5A are 2500mAh, just like the 25R.
Now, with the advent of the Samsung 30Q for the past year and a half, I've been using that. Brown LG have the same capacity but only a 15A limit while the Samsung 30Q has been tested by Mooch having 20A. 30Q are my battery of choice, can be had fairly inexpensively, while I keep my share of Sonys to power mechs or high powered 300W mods with attys. For the most part, except for the brown LG you can use them anywhere, and yes, I have some 25R still lying around after 2 years.

20a? And that one is available where I order and only $1 more. Even the 15a is probably enough for me in single battery mods I just didn't trust seeing them stated as 15a and actually being 10a. I'm willing to give those a try next time I order.

My local is still stuck on the LG 3000mAh, I find they drop capacity quickly and soon you're charging longer for less time than the 25R. 25R doesn't have as much initial drop and then keep going. If the longevity of the 30Q is the same they could become a new favorite. I was just leery of 3000mAh claims because of the LGs.

The CDR of the Sony VTC5A is only 25A, not 30A. The CDR of the Samsung 20S is 30A, and, in addition to that, down to 3.2V at 30A continuous the VTC5A can deliver only about 900mAh versus more than 1150mAh for the 20S so because the 20S hits noticeably harder at this kind of high current load, on the 18650 mech the 20S is the new kid in town.

Many people (me included) never pull anywhere near that much current from their cells. ;)

This is why people smoke, cigarettes, its too easy to go in a store and say "Marl Lights" pleae.

I don't have the time time keep up. The local vendors look at me funny when say, "just a regular tobacco flaver - nothing added". They don't have a clue about their inventory.

OMG, I knew I should have opened a Vape Shop in 2009.

I've got a stack of 25Rs and VTC5a and they've served me well. I have a new love, though. Last month I picked up a few sets of Samsung 20S and have been using them exclusively in all of my mechs. They're only 2000 mAh but that 30A rating lets me build lower safer.

Fantastic batteries. I always have a charged one on deck to swap out since they don't last quite as long. It's been worth it, though.

As I said, cheap, available, reliable.

So you're claiming the 20S is underrated on mAh? Because the tests don't show that.

Or are you claiming I need 60a of battery for more money and less run time?
You spend your own money. I'll worry about mine, thank you.
As I said, only a buck more expensive so still pretty much equally dirt cheap, available also, reliable more so than the 25R because of the CDR difference (only 20A for the 25R versus 30A for the 20S). But two boatloads of extra performance in addition to that because the tests do show that, down to 3.2V, the 25R at 25A continuous discharge can deliver only about the same mAh that the VTC5A can deliver at 30A continuous discharge, and, anyone who listens to Mooch knows that you have to look a the Wh (watt-hours) instead of looking at the mAh measurement. Wh equals V multiplied by Ah. (Ah equals mAh divided by 1000.)

If there's a cult, I'm a member. I like 25Rs. I also like HG2 "poop sticks" and which have 500 mAh more capacity. I tend to use the 25R/HG2 in regulated mods and to marry. I usually use HD2/HD2C/VTC5A in my mechs because I like the thicker safety margin. As to which one I favor, it depends on which one is on sale the week I'm buying. I have a handful of VTC5As, but I don't buy them often because they're in high demand and are not often on sale. Then again, I've been on board the battery safety train since even before I started reading @Mooch 's blog, and I don't allow myself to come anywhere near a full load, never mind an overload, on my cells.

Yes they're only 2000mAh, but because their voltage sag is so much smaller than that of the VTC5A, they run at a higher voltage than the VTC5A, all the way down to 3.2V, if discharging them at 30A.

Sure, but if you're pulling only 15A per cell, then you still have no real reason to still get the 25R excepting only if you can't get the better cells due to where you live or due to whatever, like I already said. At 15A per cell, the cells that perform better than the 25R are fairly numerous (e.g. VTC6A, 24S, VTC6, 30Q, HG2).

At 30A, the 20S is clearly superior. But at 10A (and a lot of us vape at 10A or less!) the advantage at the beginning is rather minor, and it falls behind the others pretty quickly.

I'm sitting here puffing (not huffing!) on a mech squonker -- at 0.75Ω. I'll stick with 3000 mAh cells like 30Qs, HG2s and VTC6s, thank you very much. :)

TBH, I would take an original VTC5 (no 'A') over a 25R.

I use them exclusively in mechs so I can build lower. I run higher mAh batts in my regulated devices.

Sure, at 10A the 3000mAh cells (VTC6, 30Q, HG2) are superior, and in fact I never said that they aren't, albeit the VTC6A is "only" 2900mAh, yet, despite that, at 10A the VTC6A outperforms all three of these 3000mAh cells. That is, by a fairly small margin, but the difference is there, and, what that means is there are at least 4 cells that, at 10A, outperform the 25R so thank you for proving my point, which was that the 25R is no longer worth getting excepting only etcetera again etcetera etcetera. ;)

LG browns haven't worked out for me. Runtime at 30w is less than 6 hours. 30Q last me a little longer AND more charge cycles. But that depends on the mod, vaping style and atty attached.

And that is where tests fail. The reason I don't go local and get the LGs is because their capacity drops very fast. Then you're stuck with long charge times and less run time for more money.
Longevity is also an issue to be considered. In my experience the LG turds don't have it, 25R green do. So in that sentence you are telling me 25R are worth getting since you say HG2 is better when I know from experience it isn't in the long run.

Sure, at 10A the 3000mAh cells (VTC6, 30Q, HG2) are superior

:confused: You just got done saying 20S for everyone because it's what suits you.
Since I am exclusively TC I'm at 10a or slightly less for a split second, the rest of the time I'm in the low single digits. So should I pay extra for that hard hitting wonder batt with less run time or should I pay extra for mAh? Or should I pay less for good enough that lasts for years?

Since 30Q can do 20a and I trust Samsung to make a long lasting battery that sounds like a good newer battery for me that would be worth the extra $1 to try. Not the 20S.

That was my LG experience. They drop drastically with a few charges. Enough so that against my NCR-B (I think that was the 3000mAh Panasonic) I questioned whether they were even close to 3000mAh.
25R drops some in the first week but not drastically and then they last.

I think I'll call around next week and see if I can find 30Q locally.
