Folomov 18700 cell with a built-in powerbank?
https://www.gearbest.com/batteries-railway/pp_009708949923.html

I’m liking Folomov more and more. They need to switch to USB-PD instead of proprietary cables though.

Anyway, put it in DQG Tiny to have the smallest and lightest flashlight/powerbank out there.

Fenix ARB-L16-700UP – Fenix’s second 16340 with a built-in charger, supposedly a higher-discharge one.
I don’t know any EU source for it, HKJ, if you’re interested, I can look.

Hi HKJ, I would have another suggestion to make you on a cell of a format little standard, the “Zhiyun IMR 26500 3600mAh / 13.3Wh” or existing also in another version of rewrap the “EVO Gimbals IMR 26500 3600mAh / 13.3Wh “, I would be curious to know the continuous discharge capabilities knowing that the device that uses them (the Zhiyun Crane-M for example, a stabilizer) can fired up to 6 continuous amps. Here are some pictures and links to places where you can buy them.

Cells rewrapped by Zhiyun

I do not mean to sound too judgmental, but the price of these Zhiyun cells is offensive, outrageous. Totally looks like whoever has designed such device is just trying to milk the cows. Seems like the previous version of the Zhiyun used standard 18650 cells, they could have gone any other industry standard format this time, like 26650. This totally smells like I said above. If it were me, I would say some kind Flat Stare words to that people in that regard.

All depends on the site where you buy them because I only gave links for purchase as an example, it is not the best prices of the net that I chose specifically, for example look at this one: https://www.hobbygaga.com/en-2pcs-3-7v-3600mah-26500-battery-for-zhiyun-... , the price of 2 batteries 26500 3600mAh is 12.89 € ie 16 $ This is not very expensive for two cells in this category.

According to https://18650.uk
Vapcell 21700 4000 mAh is Sony US21700VTC6A
And Vapcell 21700 3960 mAh is Samsung INR21700-40T.

HKJ do you happen to have them in the queue?

I prefer to test the cell marked with the Sony/Samsung name.

Sorry about not saying yes/no to the other suggestions, but I am a bit slow to decide what cells to buy.

It appears that Klarus has added the same cell to their catalogue now:
http://www.klaruslight.com/index.php?m=content&c=index&a=show&catid=156&...

Again, I don’t know where to buy it yet.

It’s interesting that they claim to use a Panasonic cell inside.
I don’t see any 16*** cell on the Panasonic site…

The following are only a few suggestions, first two LiFePO4 cells for which I'd like to se how accurate are their ratings (33A continuous and up to 1800mAh in 18650 cells is interesting):

https://eu.nkon.nl/rechargeable/18650-size/heter-enerpower-18650-lifepo4-1100mah.html

https://eu.nkon.nl/rechargeable/18650-size/heter-18650-1800mah-5-4a.html

 

Finally the much acclaimed Samsung 20S, theoretically tested before in a Vapcell wraphttps://eu.nkon.nl/rechargeable/18650-size/samsung-inr18650-20s-2000mah-30a.html

Various other interesting cells in nkon's lineup.

Hello? Davie

I remember having suggested the Samsung ICR18650-32A in the past here (#384) and there (#465), guess it was forgotten and/or something went wrong… Question

How about the above LiFePO4 cells? Heter is a quality cell manufacturer, but I have seen next to no reviews of its cells.

Good question with the 32A, I have tested them long time ago, but did not publish it when I found out it was at the wrong voltage (4.2V charge, they are only about 2700mAh at the voltage).

I have some cheap LiFePO4 in queue and I may also look at your last suggestion, but 20S is not in stock.

Mmm, none of those EAIEP offerings look appealing?

We can be glad we can buy lots of first OEM batteries in their original industrial wraps, which is because brave retailers manage to get and market them. However, due to the li-ion battery OEM to consumer sales reluctance/reticence I do not see an easy way to buy non-first OEM (LG, Murata, Panasonic, Samsung) cells except with a non-OEM wrap. 

China is still a bit of an isolated land with certain good OEMs and products. Since the unit price of these cells is super affordable they could be top candidates for a large battery pack, of course for as long as their performance and consistency are decent at the very least. The aforementioned ukrainians were building e-bicycle battery packs with them.

May we know which ones? A little birdie told me the wide triple leg pink wrapped “26F” cells come from BAK. I may delve in a more detailed identification if I can find some chinese indigenous lad willing to cooperate.

LoL thanks. I'd have likely chosen the same models. Both 33E and VTC7 seem to use the same cell underneath and I wonder if they could be rewrapped LG MJ1 cells. With respect to the penta-leg top 25Rs, no  idea.

That cell is likely to use one of the top OEM available high capacity cells, maybe an LG M36.

Steep pricing. I'd look for alternatives.

I believe there are no alternatives of equivalent quality.
It seems that most of usb-rechargeable 18700 cells use 18650B or similar cells, low discharge and OK capacity.
Klarus has used 18650GA in their cells before in their “3600” cells and I expect that’s what’s inside this one; better at both discharge and capacity than others. Though yes, it may come with a M36 or something similar.
Aside from a better cell this might have a lower-resistance protection circuit as well.

Just found this fairly priced sale for Panasonic NCR18650BM cells: https://www.192led.com/product/2pcs-3-7v-3200mah-10a-18650-li-ion-rechargeable-battery/

Couldn't find any meaningful review besides this video:

SKV89 mentioned this cell back in January

Maybe a high quality cell for small electric vehicles.

The cells that you propose have the same specifications as this model: https://eu.nkon.nl/rechargeable/18650-size/panasonic-ncr18650bd-3200mah-...

What are the differences between these two cell models (both from Panasonic)?

¯\_(ツ)_/¯

There's the “BD” and the “BE”, and now this “BM”. All I can say is the capacity figures that guy in the video gets, even if at 0.25A discharge rate, are rather beefy. 

I miss some formal Panasonic cell reviews.

You forget the BF and BL too, lol, it’s really unclear their name, it seems to me that the BE and BL are 7-amp cells, the BF meanwhile gives 4.9 amps it seems to me?

My informations about Panasonic cells:

BE – 1. generation of Tesla Model S 85 cells with carbon anode (unconfirmed)
BM – 2. generation of Tesla Model S 85 cells with C-SiO anode (parameters confirmed by direct comparison with Tesla 85 cells (MY2016) and many cycle life tests in my lab)
BD – is BE or BM technlogy based cell without bottom vent (unconfirmed)

BF and BL cells are based on other technology, I think BF and BL both are C-SiO anode succesors produced by Sanyo of an old Panasonic NCR18650B. (unconfirmed)

BM – 2. generation of Tesla Model S 85 cells with C-SiO anode (parameters confirmed by direct comparsion by Tesla 85 cells (MY2016) and many cycle life tests in my lab)
BD – is BE or BM technlogy based cell without bottom vent (unconfirmed)

BF and BL cells are based on other technology, I think BF and BL both are C-SiO anode succesors produced by Sanyo of an old Panasonic NCR18650B. (unconfirmed)


Do you have information about NCR18650PD, NCR18650PE and NCR18650PF?

Can a single flapping of a butterfly's wings trigger a tornado at the other end of the world?
