That looks real good! I just wonder about heat build up with the BMS. I would check it early and often once you have it running just to be safe. Especially under a high load.

Nice. If you guys are shipping surface (boat) often the shipping price won't change so even if you find a good deal elsewhere check if shipping is free otherwise it may still be more economical or close to it to buy from the cells' seller.
As @ghostwriter66 pointed out, if it's like a buck to print out 1000 nice looking stickers, I'm not sure it'd take that much digging to print them out with actual legitimate numbers; ya just end up with 1000's of the same legitimate numbers floating around.
When I lived in the Ukraine, I was also a naive Westerner and was shocked at the lengths that dubious sellers would go through to make things look real. Very often there would even be cooperation with workers at the legitimate company; one person pays another (or gifts some cognac) to a worker for some stickers or whatever; then the stickers are actually 100% real even! Never underestimate the lengths people will go through in poor countries and assuming 1st world ethics when making these transactions is quite naive even if some think ignorance is bliss.
I bet others who live and deal with the 3rd world like @fhorst can attest to this.
Living in Ukraine and now Asia I've become accustomed to investigate thoroughly, especially if a price is too cheap; I find out the level of deception going on and then decide if I'm OK with that. Last year I made a mistake; I bought a big bag of cat food that I knew was too cheap for an import and sure enough some of my cats died (so much for wishful thinking). I was already suspecting that the seller was using a "cloned" bag of the name brand product I was feeding my cats and just putting cheapo whatever inside. These things happen but Westerners aren't usually used to thinking like this when making transactions. There's a pretty sticker on the bag after all or even it's the same bag sold on the side from a factory worker! I was impressed when @Will Prowse in his review of some Titanate cells realized the sticker might just be a fake AH rating;
Digging deeper about these cells from Xuba is not an attack on your honor that you need to want other possible buyers to "take a hike"; the seller is not your best friend from high school you know. @LukeVader 's question about what email you messaged when nobody else got a response I would say should be adjusted to "who gave you the email?"
And no, they aren't doing us a favor by selling to individuals; there is a global economic catastrophe happening right now and companies will make sales anyway they can. So let's please try to consider these things before assuming people are attacking you by critiquing this excellent find.
I'm quite grateful for the find even if I'm not confident they are EVE cells; I'm still interested.
The benefit of a diverse community like this is we can work as a team to evaluate and set expectations appropriately. Please let's not discourage that think tank aspect as a tool here.
Thanks!

That is an earlier spec sheet and an updated one has been posted many times.
The Terminals are threaded M6, 6mm. Close to 1/4" US.
Page 22 Post 421 has the new spec sheet......
From the datasheet (the most recent one, there is an older one circulating):
"Remark: The pole is a double aluminum pole structure. The internal screw with size M6 is used in the
poles. The anti-torsion of pole is 8Nm. The torsion should be less than 8Nm when used. The
effective thread hole depth is 6mm."

The CONFIRMATION has been removed at the request of EVE who was upset that I posted it.
What reason there would be behind that ? I dunno, but whatever, their choice.
Such a reaction is a Big RED Flag but what it means I dunno.
Good Luck everyone.

Thats what I was thinking - put a RG45 jack on both boxes and you could connect them that way ...

"Here - Hold my Beer"
YEP - thats virtually the same thing I do but using HUSKEY boxes instead -- but the boxes are identical to the DeWalts - heck probably same Chinese factory just with different labels ... GOOD JOB ... BTW - what size are those batteries? They look ever so slightly larger than mine ...
Asked about 16cell boxes, here's the reply:
"
My supplier can provide customization. If it is iron, even one box can accept customization.
There is only one problem, if the box is too big, the freight will be calculated according to the volume, the freight will be a little high."

Get one of these Cat 6 extension cables and cut it in half. Wire one half to the BMS and the other half to the cells.
That gives you a plug and jack in a handy package.
I should order some just to have on hand it I need to do something like that in the future.

The issue is that I just don't like dangling wires anywhere outside the case .. if you put 2 RG45 cable jacks on each of the boxes you don't have to worry about that at all -- unles i am misunderstanding your concept ... PLUS witgh my way if anything ever happened to the cable you can get another one ANYWHERE ... with your way you would have to take time to remove the cable from the battery or BMS and install a new one of the same sort

What what what???? this brings up many questions and I hate to get into it but how does EVE even know about your post? Why would EVE even care about your post? As of today I have still not heard anything back from EVE on my email request. Which is why I was wondering whats the email address you sent the request to? All I was trying to figure out was if it was actually EVE or if it was another email that was given to you by someone else that may look like EVE'S email address? I've said it once before, my evidence IS this site that these might not be EVE cells. I didn't say it.... @April said it. But also like Jeremiah and ghost implied earlier it's not that hard to fool people into something on the internet. All someone has to do is create a domain like evesbattery.com or evebattary.com and they can do fake verifications from that email. I know this is a very low chance it happened to you, but its still a chance. China, unfortunately is known for stealing intellectual rights from companies all the time. Even from their own companies. Have you ever heard of 3rd shifts? Together, we can get to the bottom of this if we all stick together.

"Here - Hold my Beer"
So many of the cells that I have received have had the QR code scraped off and some flimsy black stuff not even taped on very well and obviously the top of the battery was hit by a grinder/polisher to make it look new and the blue wrapping looks new ... so theoretically its really like them putting lipstick on a pig .... HOWEVER - I run a full load test on every battery we get - PIG or PRINCESS - scraped QR code or not -- and every one of them has met or exceeded the rating ... to me THATS the most important thing ...
I use to be concerned about that - why is the QR code scratched off - and if i asked 3 manufacturers I got 5 answers ... or if i type in the QR code info that readable why does it come up to another company, etc etc ... some of the answers I got made sense .. that the QR codes are Manufacturer specific and Company A that normally sells directly to the USER (you)puts their marketing QR codes on the battery so you can order more stuff from them -- BUT Company B down the street is running low on 280's or 200's and went across the street and bought a few thousand 200's and NOT wanting YOU to know that they did not make the battery popped/scrapped the code and then recovered it (that seems to be the best answer)...
ALSO another one is that many of these batteries are stored OUTSIDE of China in warehouses in Germany and the US and technically sold as "refurbished" (to get away from customs fees and taxes, etc) and they pop-scrap the code in order to "fake" customs (you go girl!!) BUT they are actually still 100% Brand New Grade A...
Now of course if you get one that looks like its been through a drunken brawl on Saturday night and woke up somewhere Saturday half dressed and face down in the gutter - meaning - the Top is all scracthed up, the QR code is gone, there is scraping all over the blue tape where obviously it was used for something -and the black gasket on top won't even stay stuck down - then YES - you probably got one from someone that is trying to put one over on you ... Of course - once again - do a full check - if a 200 or 280 comes up with 200 or 280 respectively - then you just got battery that's ugly but still performs within the specs where its suppose to.
YES - like all of you - i get emotionally erect when the battery boxes show up and i tear into it like its XMAS morning and YES "i love the smell of LiFePO4 in the morning" and do get so ever disappointed when my new Red Ryder BB gun looks like its been shot buy someone else ((YEP I have intermingled several Movies into one sentence) ... BUT if the RED Ryder BB gun shoots straight (voltage) and shoots strong (aH) then I am fine with it ..

Gosh Ghostie, you sure have a way with imagery ! I bet your a hell of a blast at a party.
Good point...there is about an inch separation from the batteries...the BMS is 200amp rated...It's for my cottage...which we can't go to yet because of the virus...but when I get there I plan to monitor that and see how hot things get with full draw. I could also attach it on the outside and will do so if needed. I see this BMS is the brand that Will P tested... but was disappointed that his low temp cut-off didn't work... on mine it does work though...fortunately. Cheers.
