The newly upgraded samsung 30QT-6 has stronger power

this is 30QT

@Vapcell Dennis;

Prove it!

Show me some legit documentation from Samsung. Not some excerpt as you previously did.

Link a datasheet. Not FB, Not other battery types.

Try to pass PDF document on Baidu website

Comparison between new version 30qt-6 and old version

Verification Code: uawn

Can you look up the PDF file?

Can’t download the PDF but got screenshots. Album


1st- the cell is deemed “30Q6” and not “30QT-6”

2nd - this is but a minor upgrade; other than a slightly better cycle life and cold temperature discharge all other characteristics are almost the same.

Thank you very much for sharing

yeah,but only 30QT have new version in market

Maybe there will be 6 version in other places in the future

The power performance was also improved, and the samples were sent to HKJ

I have also done the test and comparison, especially the discharge end has been improved

Expect power performance to surpass Sony vtc6 and match vtc6a

High end batteries, whether in terms of power or capacity, are very exciting. Because the progress of lithium battery technology is very slow

Most importantly, the cycle life has been significantly improved

So it’s a very good cell

@ vapecell Dennis;

You don’t have to quote the entire post - quite annoying.

You should always post all info (and especially the manufacturer’s data) to be peer-reviewed prior to stating “stronger power”.

And BTW the cell is termed “30Q6”

Downloading from Baidu Cloud is always a challenge for those not inside mainland China.

I was able to find some instructions before to access the English portal, which requires entering a mobile phone number, which Baidu will send a ‘dynamic password’ to allow logging into the Baidu Cloud, and download the files shared there.

I’ve download the PDF file, hoping the PDF file can be shared publicly. Quick Google search for “upload/share PDF online” pointed to a “DocDroid” website (not sure if this is a good site or not). Download link below.

Regarding the Samsung date code.

I remember in another post that someone mentioned getting Samsung 30Q (not 30Q6) which has the date code (under the wrapper) of “L30Q” (previously normal Samsung 30Q date code will look like “L0I5” or “L0J2” where the second digit/letter is “0” to signify possibly as the item code (“0” = 30Q)

“L30Q” doesn’t seem to follow the mentioned Samsung date code format.

I noticed on the Samsung 30Q6-T, the “date code” portion also looks like “30Q”, as the following pics show:

Samsung 30Q ‘141’ below has ‘L30Q’, while the Samsung 30Q6-T below shows “R30Q”.

I wonder if the “KH1T” label (on the 30Q6-T) is a date code, and how it might be decoded?

Can someone confirm me if these Samsung 30Q are for vape or electronic cigarette, I am confused because it has written “not for electronic cigarette or vape”

guerrerohalcon, neither the Samsung 30Q nor any other battery is “for vape or electronic cigarette”. These devices are not specifically designed for such duty, they are still “power products” and their users are meant to be responsible, believe right and know how to deal with them. Indulging in vices is no license for misuse and will never be.

If you aim to safely use batteries Battery University is full of great wisdom and articles. You could start with BU-808: How to Prolong Lithium-based Batteries, his most read article.

Dear Barkuti, thanks for your reply. Actually I am a battery seller in my country, and I do not want to sell someone something that causes them a problem or injury. But I have already found out and the reason for such a note in the battery is to demarcate responsibility in the use of it. So it works for the vapos! Excuse my English, I am using the translator !!

Look at the printed 3. Legit 30Q (and 40T) have angular top not rounded. These are rounded.

(If a 40T has a code with a 3 in it anyways)

Would you happen to have sample picture?

So far I’ve gotten these different labels of Samsung 30Q - “SDI 136” “SDI 138” “SDI 141”, “SDIEM 136” and the “30Q6-T”

The 6pcs on the right side all appear to be genuine (based on capacity test, and also using YR1030 resistance meter to test IR).
The “136” might be a bit older, I measured around 12.6-12.8mOhms AC IR with the YR1030.
The “138”, “141”, “30Q-T” I measure from 11.3-12.0mOhms AC IR with the YR1030.
Capacity test also get around 2900+ mAh.
They have the correct format date code (“0” in the 2nd position) or “L30Q” / “R30Q” as mentioned above.
They also arrived from shipping condition to be from 3.35v-3.45v. (the YR1030 resistance measurements above are tested from shipping condition)

(one of the 30Q “SDI 136” has a rounded “3” and the other has a straight dots “3”, but they test the same (capacity & YR1030 IR), so I would suppose they are genuine, but with slightly different fonts. The SDIEM has a slightly different font too.

Only the left side “30Q” does not appear to be a genuine 30Q (I got it from Fireflies flashlight) — its capacity tests similar to genuine 30Q, but the AC IR is around 21mOhms (YR1030), plus the ‘code’ shows a “9” (so probably a Samsung 29E?)

Well I got 3 of these maybe 18 mos ago from Amazon:

And searching internet did not find any clearly “legit” 30Q pics that had a rounded 3.

Mine were only 2200 mah. Work ok for lo drain but I definitely think I was ripped off or very unlucky and got subpar genuine cells.

Got a 40T a few months ago and noticed wrap creased and again a rounded 3 in the battery code and, searching again, did not find any legit pics with a rounded 3 in the battery code. Have not tested capacity yet.

I may be wrong, but i looked long and hard at legit sites (Liion, Illumn, etc.) and did not find any pics with rounded 3s.

Anyway, just my non-tech observation.

Fact is that they are responsible for whatever may happen to them. This is no exemption for any involved responsibilities, and yes the battery notes are meant for that. They're scared of @#$% filing lawsuits against them.

At times I wonder if they are choosing the right battery type. Li-ion was designed with gradually decreasing output voltage as it is discharged. This was probably of use many years ago, when devices had much less sophisticated electronics, to help with state of charge gauging. Nowadays electronic devices use coulomb counting and other means to measure state of charge, and I think they don't need batteries with gradually decreasing output voltage at all. LiFePO4 is a somewhat less energy dense chemistry, but its output voltage stays nearly flat along the discharge, this means nearly all the battery energy can be used without losing power output in a mech mod, while also LiFePO4 is an amazing power battery (mech users enjoy LiFePO4). These 26650 cells (made by Power Long Battery) feature outstanding power output and performed great when they were tested by Mooch. They're now for sale (check out for Vapcell discount coupons), I guess Vapcell didn't wanted to mess with them and decided to completely drop the product instead of seeking out for the safety documentation Mooch was asking, if available. Power Long Battery makes lots of LiFePO4 battery cells, but God knows.

But this is another story. What matters here is to raise people's awareness to understand that a power battery needs to be carried in some sort of proper box. Plastic battery boxes are sold everywhere, by the way.

For those of you with a wide range of “30Q” cells, it would be interesting to see the consistency of the stamping on the bottom rim of the can. I’ve found this the most reliable way to immediately spot fake cells. Every real Samsung cell I’ve checked has a stamp thats hidden just under the edge of the wrapper on the (-) end of the cell. I usually take a razor blade and cut off this lip anyhow as I usually add a clear over-wrap on my cells for added protection and to reduced rattling in most lights.

Thanks for your advice, it is always important to continue learning, your good intention is valued !!!

Mooch is the best authority in safe vaping batteries.

In short 30Q are rated for 15A but they are good for 20A as long as the temperature remains below 75C under your own risk, Samsung 25R are good for 20A. For higher loads per cell the Molicel P26A/P28A or the Samsung 20S or 25S are recommended. Somebody may attempt to run the cells at higher load than recommended for a few seconds but if the device is turned on for too long, it could easily vent with flames or worse so it’s unsafe.

Cells like the NCR18650B, the NCR18650GA, LG MJ1, Samsung 35E or god forbid the Samsung 26J or the Samsung 30A (not 30Amps!!!, I found somebody asking that in MercadoLibre) have a CDR 10A or below and are only good for flashlights and other things with moderate power requirements, their capacity is good for that, not for vaping. Anything over 3600mAh in 18650 format, like most cheap 18650s in the local market, is a fake and most likely terrible.

I think most vaping devices will work better with flat tops rather than button tops, but I never actually touched a vaping device, I only read it from the internet.

It can be done, but who is doing it (and all that it entails) matters. Absolutely.

There's people which vapes at moderate or low power levels, and may find a low to mid power cell adequate. Of course using a cell at its maximum rated discharge current is neither optimal in energy output nor cell lifespan wise. Mooch has great recommendations in this respect, but if I were to give out some rule I'd refrain from using a cell above its CDR / √2 in the absence of better alternatives; this rule is enough to halve thermal stress on the cell and also raises effective energy output. Reading reviews like this 35E one makes me think he would sort of agree.

May I ask for a sample pic of how that looks like?
