I hope so. I have PM’d Dennis and Vapcell on AE with no response so far.

No need to PM them - just request a refund on the order through Ali, that's what I did.

I opened a dispute in AliExpress system regarding the Vapcell K64, but no response from them yet. That was 3 days ago.
I suppose they’ll reply at the last minute (the AE dispute system still says there’s a few days left for the seller (Vapcell store) to respond to the dispute)..

I guess will wait it out, or maybe will PM Dennis.

That doesn't sound good. I ordered a few pieces of K64 last April 3. Vapcell/AliExpress gave me a tracking number on April 8. But that tracking number doesn't give any update at all using multiple tracking sites (17track, postal.ninja, track24, etc. sites) It's been over 1 month since those K64 have been shipped out, so if they'll discharge to low voltage, in case I receive the package, then several of them may have self-discharged to low voltages...

Did you try to ask Vapcell's customer service what freight carrier they were using? Mine are being shipped by Meest Group, probably via ship from Shenzhen, CN via Rotterdam, NL and then further to Germany. I ordered my six K64 batteries on March 27, 2021, i.e. 45 days ago. According to tracking (which also did not work for several weeks) my order it is still being processed in Guangzhou, CN. I do not expect it to arrive within another 45 days. Big Smile (…)

Well, 79 (seventy-nine!) days have passed meanwhile and my substantial order (among them six K64) has still not arrived. This is my personal new record for waiting for an order from China. After 70 days they automatically prolonged the purchase protection period by another 30 days. According to AliExpress I am entitled to request a full refund for my order (75 day money back guarantee). I PM‘ed them. They asked me to keep on waiting as there’s still movement in the tracking history.

I start getting mixed feelings how the cardboard box will look like (if and when it eventually arrives) and what voltage these batteries will still indicate. I have worries that it will be held by customs, so I probably need to bring along a multimeter to check voltages before paying any import taxes for dead batteries, lol.

Dennis, if you read this: No offense but shipping via Meest Group seems to take an eternity from Asia to Europe…

Well Vapcell offered me any other batteries in their store so I chose the T50. They then said that would cost $10 more. I then requested a refund and they said I had to raise a dispute. AE will not allow me to raise a dispute so unless Vapcell can refund me without me raising a dispute I will have to go through PayPal. Disappointing.

Nobody in their right mind would accept a delivery time of 3 months for the T50S. It’s madness!

I suppose that depends on which country is the destination..

A few years ago, I didn’t know where to source the better branded 18650 batteries in our country (I’ve tried a few different local vape stores, but they didn’t seem to have genuine batteries, and most do not seem to know how to check for genuine batteries since very few people know how to do so). Thus, I tried sourcing from foreign stores. Many stores do not ship to my country. But a few do. And out of the few that do, sometimes the shipping method does not push through (shipping/tracking will stop at some point and the package never arrives). I’ve been willing to wait around 4-5 months for the batteries to arrive, IF they arrive.

As long as the battery is in proper storage condition and is the genuine good quality, I’m willing to wait a longer time, rather than not.

For instance, I’ve been wanting to purchase 26800 batteries so I can try them out. Unfortunately, no seller ships 26800 to my country (at least not without a minimum order quantity, I found a store that is willing to ship 26800 batteries to me, but require at least 100 pieces quantity).. so I’m still waiting for a store that can ship to me the 26800 battery. Already waiting more than 1 year for that battery to ship (economically) so I can check it out..

Just get someone to forward you a couple. You’ll have to pay double the postage but it’s better than nothing

At last, my order from Vapcell has finally arrived. As promised before, I report my observations here:

 

Order date: March 27, 2021

Delivery date: June 17, 2021

Total order processing time: 82 days

Routing via Meest Group / Hermes: Guangzhou, CN – Hong Kong, CN – Istanbul, TK – Amsterdam, NL – Berlin, DE

 

Scope of delivery:

6x Vapcell K64 6400mAh 26650

4x Vapcell S30 3000mAh 18650

2x Vapcell F14 1400mAh 18350

2x Vapcell M11 1100mAh 18350

 

Observations:

 

Packaging was alright. All batteries came in those black Vapcell pouches (2 pcs per zip bag) or inside a plastic case (18350 cells).

 

Battery type K64 S30 F14 M11
Voltage #1 0.25V 3.61V 3.88V 3.87V
Voltage #2 0.26V 3.61V 3.89V 3.99V
Voltage #3 0.26V 3.62V    
Voltage #4 0.16V 3.61V    
Voltage #5 3.80V      
Voltage #6 3.73V      
AC 1kHz impedance (measured via SM8124A) 11.2mOhm - 11.8mOhm* 10.2mOhm - 11.2mOhm** 52.7mOhm - 53.6mOhm 21.3mOhm - 21.9mOhm

 

* Surprisingly, the overdischarged state of the K64 did not affect the battery's internal impedance. The readings were more or less consistent regardless of its actual voltage.

** The general impedance was consistent at 10.2mOhm but the button top adds approx. 1mOhm, when the 4-wire probe measured from the button.

 

Verdict for K64

4 of 6 K64 batteries are dead. I will not even think about charging them up. I notice a substantial voltage variation between cell #5 and cell #6. It will probably take ongoing surveillance of self-discharging for these two cells to make sure if these are safe to use. High voltage variation seems not a good sign, though. Shrink wraps are more or less attached in a proper manner. However, they could be attached more precise, see pictures below. Batteries are clean and show no signs of corrosion or wear.

 

Verdict for S30

All 4 batteries show normal parameters both for voltage and impedance. All voltages are more or less consistent. I did not measure very accurately for more than two digit counts. Shrink wraps could be made more accurate and are not attached in a good way. There is a high risk that the shrink wrap will fall apart during heavy use. I found hairs and greasy debris on the outer shrink. One cell of those 4 shows signs of damage to the outer hull on the negative pole (rust-brown hole in the steel). I cannot judge how safe it is to use for long-term use in a flashlight were springs will cause wear and tear to that area.

 

Verdict for F14

Both batteries show normal parameters both for voltage. Impedance (approx. 53mOhm) looks rather high for an unprotected battery but it might be alright for a high capacity cell. Shrink wraps are well-attached and clean. No signs of corrosion or dirt.

 

Verdict for M11

There is a significant voltage variation between cell #1 and cell #2. 3.99V is definitely way too high for storing batteries. Since the other battery shows a more or less good storage voltage I suspect quality fluctuations on this cell. To be fair, it will take a longer observation to assess any high self-discharging. Shrink wraps are well-attached and clean. No signs of corrosion or dirt.

3.88V is also too high, that’s something I have noticed with Chinese cells, they are often stored at high SOC, which is detrimental.

Just to share regarding my order of the 8pcs Vapcell K64. 1 battery arrived at 3.77v, another one is 2.1v, and the remaining 6 pieces are all less than 1.0v (0.15-0.85v)

.

I used the AliExpress dispute system, the store offered to send some other battery type.. unfortunately I could not see any batteries listed anymore in Vapcell's AliExpress store. It looks like they do not ship batteries again to my country (I was able to check batteries, after I set the "country" to another country that's not mine).   Since I couldn't check which other batteries I may be interested in (ie. I couldn't properly determine the prices of "other batteries" that they can send as replacement, I rejected this proposal.

The next option that came up was to offer a refund for the 7pcs K64 (1pc arrived at 3.77v, and that was deemed as a "good" battery, so that "good" one will not be refunded.  Refund amount will only be for the 7 pieces overdischarged Vapcell K64.

 

~~~~~~~~

 

I tried to monitor the 1 piece Vapcell K64 that arrived at 3.77v (I didn't charge this battery yet), but the next day, I decided to start religiously monitoring its voltage, and this is what I got.

start of monitoring:  (I use a Fluke 117 DMM to check voltage, and didn't use the battery at all during the entire time)

day 1: 3.768v

after 1 hour : 3.769v (strangely it increased by 0.001v)

after 10.5 hours: 3.767v

after 24 hours: 3.766v

after  34 hours: 3.765v

after 49 hours: 3.764v

after 72 hours: 3.761v

 

0.008v drop in voltage after 3 days, is this still considered a "good" battery?

Vapcell K64 battery is still undergoing technical improvement. If it can pass the tests, it will continue to be sold. It is expected to take several months.
Is there any progress? Does anybody know?

I thought I was lucky with my Vapcell K64 26650. After receiving the voltage was 3.8V, after a month it was 3.7V. And then three more weeks passed and the voltage became 2.5V. Sadness. So be careful.

Sorry for my poor english.

That’s not too bad, compared to the ones I got. As mentioned in an earlier message, I got 8pcs. 1pc arrived at around 3.77v, another arrived at 2.0v, and the rest are between 0.1-0.8v.

Since I felt like experimenting, I tried to slow charge them first, until they got to usable voltage (3+ volts). I monitored if the battery’s temperature is getting warmer (some of them did get slightly warm, but not too hot).

Feeling more brave, I decided to charge them up to 4.20v (I use SkyRC MC3000 with temperature cut-off, so in case temperature gets warm, the charging should cut off.

In any case, 3 of the batteries are getting much warmer (40+ degrees Celsius; although being in a tropical country, basically our room temperature would be something like 30+ degrees Celsius basically whole year round). I noticed that those 3 just would not get to 4.20v even as charge current kept on decreasing (Constant Voltage phase of charging). I manually stopped the charging when the batteries won’t charge to 4.20v after maybe 1-2 hours. Did a discharge capacity for all 8 batteries, and about 5 of them only had around 5000+ mAh capacity, while 3 of them had around 6000+ mAh capacity (from full down to 2.50v cut-off at 1Amp discharge current).

Decided to charge all batteries to 3.70v and start checking which ones will self-discharge faster. As noted, the 3 that refuse to full charge, started to self-discharge faster (and actually the battery felt a bit warm to the touch compared to the slower-self-discharging K64). So, it means the batteries high “internal self-discharge” is being translated into heat (I was afraid at this time, because, will the battery vent or explode? I’ve not experienced venting or explosion yet from li-ion batteries before though…)

Anyway, placed the batteries in a non-flammable surrounding and started checking voltage. The fast self-discharge were already below 3.0v within 24-36 hours. While the slower self-discharging K64 took maybe 3 or more days to get to 3.0v. I didn’t try recharging the batteries and stopped monitoring voltage after around 3 days.

On checking, all batteries got discharged further. I want to try testing the batteries again, so I got the 3 “best” K64 (those that self-discharge slowest when I charged them to 3.70v)

So charged them to full 4.20v. They charged to 4.20v without problems. I hadn’t removed the batteries from the MC3000 charger yet, but maybe after an hour , the MC3000’s fan automatically turned ON (meaning it detected a hot battery, even though charging has already stopped about an hour ago or so. I immediately checked and one of the batteries that charged to 4.20v, is getting WARM. This scared me somewhat. Immediately removed the said battery, and I thought to immediately discharge the warm K64 battery using a cheap generic flashlight (so placed the WARM fully-charged K64 battery inside a cheap generic flashlight to drain the battery, set to a low-medium brightness level – I think that generic flashlight uses less than 1 Amp for that brightness setting). It took several hours to drain the battery, at least it’s not warm anymore after getting discharged.

In summary, even the previously “good” K64 (even the one that arrived at 3.77v), it now experiences fairly fast self-discharge (won’t last 1 week before it gets to below 3.0v). Although I just charged them to 3.70v (MC3000 allows ‘storage’ mode and configurable charge/discharge end-voltage setting)..

So, none of the 8 K64 are really “good” as all of them self-discharge fairly quick. It seems that charging them to Full 4.20v is a main cause for the battery getting faster self-discharge issue. (I don’t suggest to test these batteries without monitoring temperature and exercising caution…)

My 2nd of 2 K64's that seemed to hold a charge doesn't anymore. Oh well, no loss with the full refund given.
