Samsung INR21700-50S

Thanks Lux so tempting (: I have six 30T’s and three 50S’s which are good for my 9.3 home lights. I have my 2000K E21A running for hours a day.

So I bought a Graphene power bank a few months ago and it’s rather amazing. It holds 20,000 mah and recharges from zero to 100% in like 45 minutes. It outputs 100 watts which is enough to run my HP laptop

I wonder what kind of cells it has inside …

Hi! As I’ve mentioned earlier in this thread, LG has the INR21700H50, 5000 mAh, which is rated at 25A, according to Vapcell’s Facebook account.

Hi! How do you know? Do you have a link or something?

I mean the cell inside that Acebeam battery, in the video I posted, is a M50 which is also a quite good cell. So maybe, probably, it isn’t too bad for a protected battery with USB charging, but it’s neither a 5100 mAh nor a 20A cell.

Most of us know that some crap-fire batteries marketed as 10 000 mAh should be avoided. Acebeam, Nitecore and the likes do not offer crappy batteries like that, but this is just another example of them not really being trustworthy and I hate that.

Haha yeah. My buddy asked for advice on getting a flashlight (don’t you love that?) and after I have him some ideas (i.e. Emisar D18), he sends this link for a little 90,000 lumen flashlight from Amazon for $20

Meanwhile I went out for a walk with my Imalent MS18 tonight and the thing is massive and… $600

I had an interesting talk with Vapcell yesterday. It seems Vapcell is one (or maybe even the one and only) exclusive reseller of this powerful Samsung 50S battery. Samsung is apparently forbidding direct distribution of its 50S battery, i.e. it will probably not appear as bare battery like 30T or 40T in known battery retailer shops. :-( Since all Samsung batteries can be traced back by their serial number it would be a bad idea for a retailer to illegally sell the naked battery to customers, facing severe consequences in their business relationship. Let's hope Samsung will change their mind eventually.

I also hoped LG Chemicals new H50 battery to be a direct competitor to Samsung's 50S battery. According to Vapcell the H50 turned out to be as good as Samsung's 50G but not as good as the 50S. (picture borrowed from mysku.ru)

Yeah but I mean, Vapcell is obviously biased toward themselves. IFAIK Samsung and others have always forbidden direct sale of cells, but maybe they put more effort into preventing that since the LG exploding cells thing early 2020. I noticed that recently Nkon added the 50G and they are not with the original wrap (yet are sold and appear as new), they probably had to find alternative sources for them (when I contacted them in September they couldn’t find any source for them), hopefully the will be able to find alternative source for the 50S too.

I predict that given time, these cells will be widely distributed… that is my hope anyway.

?

Could do a group buy. I’m sure 100+ pieces would be snapped up.

If they’re genuine, I would be in for 10 pcs.

TomE mentioned his actual measurements here

Same here. If the real deal and a GB is a go, count me in for 10 pcs as well.

I’d chip in for 10 as well.

Just sent an email to EVVA Tech regarding the possibility of lowering the MOQ to 50pcs. And if set at 100pcs (or 50pcs), the total cost including shipping to Los Angeles. Let’s see what they say…

I measure the discharge capacity of the Vapcell T50 and it is super impressive at 5120, 5101, 5021, 5214mah !

I hope they do sell them. We do have to verify that they’re genuine though. Perhaps someone at illumn might be willing to do so, or HJK.

Exactly. The actual hope is that a shop such as Illumn is willing to take notice and help push this along. I am merely fishing for ballpark cost. And maybe a sample pair :slight_smile:

Vapcell is selling them. The price is quite high but at least there’s the assurance of legitimacy. Newest Product Vapcell T50 Inr21700 High Capacity 5000mah 20a Rechargeable Lithium Battery For Flashlight - Buy Vapcell Inr21700 T50,5000mah 20a,For Battery Pack Product on Alibaba.com
