I just got two to add to my growing collection of 25r.the new Samsung 20s (i think that's the name)the light blue one is supposed to be great.mooch told me one day I was chatting with him on facebook.I told him how I had a .07 build on a 30q and he told me I should change to a 20s said it can take whatever within resin.but it's like 17$ a battery.it's ok I'm moving over to 20700 and 21700 next month.
I would expect the light blue wraps are superior to the old 25R light blue wraps.
The current green 25R wraps are decent but the previous light blue ones (years ago) were flimsy poc and tore easily.

I heard alot of people say that a 25R will outperform any new 18650 battery and people say they have a cult like following. I have used 25R,s for years there reliable, cheap and easy to find. I was wondering if anyone is still using there 25Rs or has everyone switched over to sony VTC 5As
My extremely trustworthy local B&B always has 25R's in

I posted the wrong Mooch video previously. This one (Episode 5) compares the curves for 30Q, HG2, and VTC6.


If you navigate to 6:58 in the video below you can also compare the curves for VTC5A, 25R, and VTC4.



As everyone can see the 25R is just a poor battery in direct comparison to the VTC5A, and the real-world performance also reflects that because Mooch's test results never lie despite there will always be people who will insist that they know better.

Noone denies a fresh VTC5A is the better performer of the two, but it also comes at double the price of the 25R, and it isn't that readily available.
Btw, most of the time you get the VTC5A at a discount, it's because of overstock or because they're slightly more aged.
That's why I said what I said about the Samsung 20S, here:
Samsung 25R Cult?

So for like only an extra dollar over the 25R you can get an 18650 battery that very noticeably outperforms the VTC5A.

I don not really understand, why people have to argue over and over about known facts :D
No one compares the performance of VTC5A and 25R at high currents. But if you vape with up to 40 Watts, what lots of people are doing and your battery should give you not more than 15A CDR, you can use 30Q, HG2, or VTC6 and you will get longer running time.
And if you vape at 20 Watts (like I do), the INR18650-35E gives me much longer running time, than any VTC5A, HG2, VTC6, or 30Q.

The right battery depends on your vape level. For 10W to 30W vapers a high MAH cell with the highest amp rating within the higher MAH range is best. It's MAH that gives you maximum vape time. Amperage allows higher current loading for high watt vapers. Above 30W you begin to max out the load rating of a VTC6. 25R and 30Q might be the next step if you are looking for higher MAH with beefier amp ratings.

Matching cells properly to the task is important. Most of our mods provide amp draw displays these days, so we all know how much current load rating we need to match with the MAH rating to yield longer vape time.

At 20W you are under the 8A CDR norm on that cell, probably in the range of 7 amps or so. The max discharge curent is 13A, so you have some padding there.

Pls. take a look at Mooch Video on youtube:

30W / 3.2V / 0.9 = 10.4A
20W / 3.2V / 0.9 = 6.95A

The display does not refer to the current withdrawn from the battery directly.

I didn't hear them say 25R was a poor battery nor have I seen anyone saying it beats VTC5A.
25R is cheap, 25R is available and 25R is reliable.

If you want to play, "what is the best..." game for yourself that's your business.

What I said about the VTC5A is true for the 20S as well. I bet you get the 20S that cheap only, if it's overstock or a more aged cell. You always just get what you pay for.;)

I think the video I linked is actually crystal clear about why the 25R is just poor performance in direct comparison to the VTC5A. But my other point was that the fact the VTC5A is no longer as widely available as it used to be is largely irrelevant because the VTC5A is poor performance in direct comparison to the 20S, while the 20S is much more widely available than the VTC5A right now as well as is only a dollar more expensive than the 25R the performance of which is not just poor, but downright laughable in direct comparison to the 20S. The simple fact you hate battery performance or you just think you don't need better performance, isn't going to change anything to the fact better performance is better performance so the only real reason to still get the 25R is if you can't get anything better due to where you live or due to whatever.

I own a large enough number of both of these two batteries to know that the performance gap between the VTC5A and the 20S is actually a very far distance away from being subtle so I read through remarks like these as if claiming there are no colors in a rainbow.

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.

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.
