Wh and Ah and More

On mobile so I’ll find a link soon, but this was I thought earlier this year or 2022.

I don’t judge easily but the evidence I saw wasn’t good for SFK’s case. However I do take in the fact that SFK never spoke their side of the story and there are always two sides or more to any claim. But I will see if I can find this thread.

Well I asked Dwayne from SFK repeatedly to join Diysolarforum and they said the kicked him off in 2021 when he told people that Alibaba was selling grade B 99.99% of the time and unless you had a test report it was grade B.

IF you are referring to 280K v1/V2 test they all test below 280, and grade B test in the 260s this has been well established. Which is why EVE is now releasing V3. Or at least attempting to...
 
Tim you seem to get super upset anytime SFK is mentioned are you worried 18650 might loose sales to them? Certainly seems like it. Please tell us about SFK's "shadyness" I have over 86 cells from them and have 48 more coming.

Would you like to hear about 18650 shadyness? How about blatantly lying about grade B cells that are guaranteed to pull full capacity and then telling the customer to F off afterword? Btw they have done this to plenty of people and you seem to be perfectly ok with it.

the Amazing 304 that actually only test to 267: https://diysolarforum.com/threads/e...store-zke-40-testing.60568/page-3#post-752497
What were the results of your 3rd party test?

I would never order from SFK based off the theatrics here.

Full disclosure I would also order more LF230s from Docan if the price were right, despite all the bad PR

Perfect example of the ridiculous double standard, Docan world famous for selling counterfeit sanded of Re-lasered QR codes are OK with you but SFK being mean to scammers is not. Good to know!
 
While not the biggest consumer of the 18650 Store EVE LF280K cells, the (36) cells I have from them ALL test above the rating.
EVE LF280K V3 cells test at 299ah-304ah, earlier versions all 284ah-286ah.
I would buy from 18650 Store again when I need more DIY Battery Bank cells.
You drove down to 18650 store to do local pickup, correct? How was the experience? I haven't pulled the trigger yet but prices are coming down so it may be time. Just a few hours away from me.

Do you have a copy of the test report from the V3 from 18650 store? Can you post a screenshot I need to confirm what SFK is saying are the round terminal dual pole 280K really testing below the octagon versions?
 
Tim you seem to get super upset anytime SFK is mentioned
I'm not upset at all. I didn't buy anything from them.
are you worried 18650 might loose sales to them?
Not at all. 18650batterystore has enough trouble keeping stock.
If more people buy from other vendors, I'll have a better chance of getting cells whenever I want.
Please tell us about SFK's "shadyness"
You have quoted it yourself. So, you are well aware.
I have over 86 cells from them and have 48 more coming.
I'm glad that it has worked out for you. I don't wish anyone bad luck.

I can only recommend vendors that I have purchased from. But others have recommended many other vendors that they were happy with.
All of my opinions of vendors are based on information I have found in this forum. That's what it's here for.

You missed the part of my quote where I purposely bought grade B cells from 18650.
I would not buy 280s from Docan but like I said I'd buy 230s from them again if the price were right. World famous? Wow.

Being mean and digging up someones personal records and slandering them on youtube are 2 totally different things in my book (yea SFK removed that video...)
He has an online YouTube channel and confirmed my results the cell was bad, he said he may do a video but I don't know.
Right.... Have a nice day. I'm done arguing. Let's get the thread back on track.
 
Bro, wtf is up with this 280K this is one screwed up line of cells man. I just realized the dual pole 280k are NOT octagon terminals! Looks like EVE is up to some BS again!
The logical conclusion is those round terminals are in fact v2s being sold to purge out inventory of the V2, versus octagonal v3s that potentially may not have issues down the track like V1 and V2.
 
Do you have evidence of this or just your personal opinion, I reviewed many of there claims did not find any major discrepancy. In fact does anyone have the capacity report sheets form 18650? They say they email these to you when you place an order, we can get an answer for this if indeed the dual pole cells are testing lower or not.

I know that SFK was busted for misrepresenting their grade B cells

When was this? You have a link?

Here’s the thread I was looking for earlier. There is another thread referenced within it that’s also worth reading.

Just to throw it out there, but I've bought from Sirko quite a few times and I knew they weren't Top Of The Line 110% rating Brand New Super Grade AAAAAAA batteries, but my 52Ah batteries came it at 51.8Ah, and my 100Ah came in at 99.7 so for the money I saved was still a really good value for play batteries and small projects. About the only complaint I can think of from all the things I've bought is that the JBD BMS's I get from them don't talk to the Overkill app. ?
 
Wait I’m confused. I know that SFK was busted for misrepresenting their grade B cells, but I thought we were talking about 18650 battery store here. Did they also misrepresent?

That's news to me sounds like you are pulling stuff out of your rear. ?I have cells from 18650 and SFK both had test reports 18650 emailed me an excel file and the 48 cells I just got from sfk have all the cell testing data on each cell.

While I don't agree with a lot of what Alkaline says, his post pretty much took all credibility from RayfromTx as far as I'm concerned: https://diysolarforum.com/threads/sunfunkits-show-their-true-color.44653/post-676976

280K cells v1 and v2 all test just slightly below rating, even the dual pole I have from 18650 tested to 278 AH, I still liked them, but I have sanded off the tops of the holes as it appears the dual pole have anodizing that needs to be removed. If you don't like the results you need to go ask EVE what the problem is 18650 and SFK are just showing what was given to them by EVE.

Meanwhile the company that the RayfromTx keeps telling everyone to buy from does stuff like this: https://diysolarforum.com/threads/docan-power-bad-experience-beware.61866/post-773779

I’m sure SFK has good cells. I had high respect for them until I read the following two threads (second thread within the first). It doesn’t look good on SFK’s part. Since they have not come on here to clear their name, I’m left with threads like these.

Seems like everyone has something bad to say about some seller, so I do keep in mind that it matters who says what. Some users here I respect their opinion more than others based upon their post history.

If and when I am ready to buy cells, most likely I will buy from a USA seller. I will call them first and ask questions and see how open and honest they appear to be on the phone. I’ll use that experience combined with the user reviews on this forum. Most likely I’ll buy from 18650batterystore because I can’t seem to find much dirt on them and users I respect have bought a lot of cells from them and they STILL recommend them!

I bought a lot of stuff from Renogy and because of how they treated me, I do NOT recommend them anymore! Victron from Invertersrus.com is who I recommend now.

Tomthumb,

You said I have been here for a while, well haven't you? Both 18650, and SFK had there account removed when the vendor section was removed along with various other alibaba sellers account so how exactly are you expecting any response form either company. No company is going to want to engage in a place where they have been removed I have spoke to both Chris from 18650 and Tommy from SFK they both said (paraphrasing) Will Prowse is a good guy but the forums basically are run by third party sellers.

I remember reading those threads and I can tell you they both were accusing docan and a number of other alibaba companies of the same thing: selling grade B cells as A. Back then there wasn't the QR codes with a B so it was harder to tell, but test report existed then to but trying to distinguish between the 2 grades was very difficult. Basically the vendor forum was a big mess so its understandable why its gone.

As for the thread you point to its ramblings you have SFK haters vs SKF supporters (and you can add me to this because I have rept 280s from them, but I try to be unbiased, emphasis on the TRY). There is nothing everyone isn't already aware of and has made there opinion of.

18650, SFK, Ezealco and Now Battery Hookup all sell grade A cells with test reports, you can not go wrong from any vendor and there prices are within a few dollars of each other. Depending on the amount of cells you need you can select the vendor that suits you best. No one is buying 4 cells form SFK as there prices are too high, but clearly if you need a lot of cells they have the best price/cell. For me Ezealco would be the best if you need 16 cells as I can drive to houston and pick up them (even thought I have to pay sales tax). I think you and timselectric are trying to create unneeded BS drama among these vendors when you should be focusing on the fight between vendors that have test reports and the ones without.

If cells test to 280-290ah, is that A or B grade?
