18350 recommendation

I ordered Shockli, thanks to all for the info! Vapcell is available in stores where I live, maybe I will try it in the future.

Thanks

No current rating is given, just a “High discharge performance” statement in the wrap. My right astral ear was beeping when I found them. There’s really no way to lose here because:

There are no other 1000+mAh rated 18350 cells in the market right now as far as I know. Even Vapcell was caught “red-handed” and they had to admit and/or realize the cell they were rewrapping was changed. Their newer wrap reads a 9A rating now.

If the cells do not meet their capacity rating I go dispute and that’s about it. But they will I believe.

The 1000+mAh 18350 cell being manufactured right now has been tested by HKJ under BestFire and Shockli wraps:

The KingWeis look the same.

The shape of their discharge curves match closely, with some minor differences attributable to binning or cell grade:

Average capacity at 0.2A (0.2C) down to 2.8V was 1060mAh for the Shockli cells and 1008 for the BestFire.

yeah，Vapcell new version 1100mah 9A

That’s why I said “and/or” Pete7874.

You could ask vapcell Dennis… wait! It seems like vapcell Dennis’ posts have been removed from the forum. I was checking to see if I could find them, but no dice. Examples:

Vapcell INR18350 1100mAh retested by Mooch: shenanigans again.

There was a thread titled “Tesla sanyo NCR21700A 5000mah amazing power beat samsung 21700 48G” back in the day (November - December of 2018). vapcell Dennis started it with a bunch of graphs of their own cell testing versus others related in the same category from the main manufacturers. I have update alerts from that thread in my email. The thread has been removed. Now I understand why, all of a sudden, I noticed a steep drop in my post count weeks ago.

Cheers

Many posts were deleted because they violated the rules of the forum. :person_facepalming:

But I can apply for recovery. I can’t find links of some posts.

So if anyone knows the link, please let me know. Thank you.

Can anyone recommend a place to buy 2 pieces of Keeppower 18350 1100mAh with affordable shipping to US.

Sofar it looks to me like it costs $18-$20 with shipping.
BG is maybe $15 but still ridiculous and have a bad rep.

Caught red-handed? Yes. Realized? Yes. But I do not see them admitting to anything, at least not in the thread you linked to.

Shame, cause for a moment they had me believe they were a reputable outfit.

Vapcell is actually a reputable company from my experience and I own a bunch of different Vapcell cells. For example I tested the Vapcell 18350 cells (probably older version) at 1156/1155/1019/1149/1126 mah. I was going to retest the 1,019mah unit becaues it might be a fluke with my Xtar Dragon but they got mixed up so I didn’t want to retest everything. The 2800mah Vapcell VTC5D measures 2855/2775/2842/2866 and pushes my FET flashlights harder than the VTC6. The Vapcell 3000mah VTC6A measures 2986/2983 mah and also pushes harder than my geniune VTC6. The Vapcell 4000mah 40T measures 4038 mah and pushes the several Fireflies E07 I have to near 30T levels as confirmed with my TA lumen sphere.

It is unfortunate that the recent batch of Vapcell 18350 does not perform the same as the older batches, but it is beyond Vapcell’s control if their supplier changes the formula without letting Vapcell know. I give Vapcell the benefit of the doubt because they are well aware that there are plenty of forum members that have the capability to test their cells and that would be a big risk to lose reputation over maybe a couple pennies in savings. Also I like how Vapcell voluntarily send so many of their cells to HKJ and Mooch for testing, which I think is extremely beneficial to the community.

Last but not least, please remember Vapcell does not manufacture cells. They simply rewrap cells. If not for rewrap companies, many of these cells would not be available to the average consumer because they are not available for purchase in small quantities. Among the rewrappers, Vapcell seems to be one of the more knowledgeable and reliable ones.

I think it would be very helpful to members here if your deleted posts can be recovered because many of your posts contain useful technical information.

Btw, I was looking for you for a month already. Didn’t get any email response from the email shown on your website after multiple emails sent. Is admin@szfyte.com even correct?

Our Sales Manager hasn’t logged in for a long time. The forum administrator sent her a warning message. She didn’t respond.

Then all accounts were blacklisted

I’ll contact the forum administrator and we’ll learn the rules of the forum and apply for the resumption of some posts.

Contact me later, I will always be online.

Finally back Dennis? In any case it’s nice that you’re back, I never really why the Administrators had blocked you, whatever their reasons could not justify a blocking of your account, this is my opinion.

VapCell aka #NumberOne

Dennis,

I would appreciate your opinion on these Purple Vapcells. Are they the same as in HKJ's review

(1) "Vapcell 18350 1100mAh 9A Battery"

(2) "Vapcell 18350 9A Flat Top 1100mAh Battery - Genuine"

Thanks man.

Thank you for your attention to vapcell batteries

Yes, the same factory produces, but with a little modification of the formula, it reduces the capacity and improves the power.

Product consistency is not very good, but it is still the best 18350 batteries in the market, and we are still developing better 18350 batteries.

Just a small update. The KingWei 18350 1000mAh cells have been thoroughly tested:

Capacity figures are 916, 897, 902, 896, 899, 895, 882, 886, 913 and 890, all mAh values discharging down to 2.8V barely at ≈0.5C. Average capacity: 897.6mAh.

Cold cell DC internal resistance numbers are 105.22, 104.67, 111.11, 110.22, 108.22, 110.22, 117.44, 116.33, 112.33 and 111.44, all mΩ values taken at a liiiiil below 20°C. Average: 110.72mΩ.

Thanks for reporting.

How many Amps can you pull from these?

Barkuti · 2019-03-14T10:02:08.000Z

Sorry if I forgot to say. Battery weight was measured at 216.7g for all 10 pieces in my kitchen scale if I do remember right, will recheck later.

Check this album for pictures: https://gifyu.com/album/swr

With regards to discharge performance can't say for sure, but check this related review: LiitoKala 18350 900mAh (Pink) @ lygte-info.dk

While the above cell features a different top, review measured capacity, internal resistance and even weight are nearly identical.

I'd say its discharge performance is ≈5C or 4.5A maximum. Good cell for up to ≈3A of effective drain.

Cheers

Thanks, Barkuti.

Just curious, what were you testing in the below image?

Barkuti · 2019-03-14T17:54:02.000Z

Pete7874, 18350 cells are short and therefore spring rail pressure is loose. By sticking another 18350 by the other side that is fixed just enough. :-)

Cell weight re-tested and confirmed, they're within ±0.25g or so.

Cheers
