Need EVE 280K Batteries: Luyuan? Qso? Docan? Other Companies?

Pillar 6)
Dealing with a company (regardless of location) that has repeatedly delivered exactly what was promised with a good track record with numerous clients. You know, the "Known Good Vendors" with a good history.
Great point. Sometimes even a state side supplier can turn sour. Perfect example that I will leave rest is a former group buy.

After hearing so many positive reports from a number of members including @Steve_S about Amy Wan Owner of Luyuan I decided to test the waters with a purchase. I have been more than pleased and impressed with the results.

Even after the purchase, Amy has responded to all my product questions with technical schematics, photos, information, etc. After reading multiple threads about long hold times for technical support from state side companies I will leave nameless I am pleased to say that this supplier goes above and beyond to provide both excellent products and services.
 
Seen that happen on Amazon & Ebay as well...
Reality Check: There are Scammers EVERYWHERE and more "schemes" to liberate people from their money than any of us can count regardless of what continent or nation you are in.

It is FAR more likely to happen on alibaba or aliexpress unless you do your homework and research the seller and feedback.

I have well over 2000 ebay transactions according to my feedback which means likely over 4000 in reality and ive only been burned once there.

amazon is very good about refunding the buyer if something goes wrong.

I have many purchases on aliexpress and yes the first time I purchased cells there I almost got scammed but I got my money back when it became clear they were scammers.
The second time I was more careful who I purchased from and everything went well, I got 16 86ah cells for $601 shipped so I wasnt expecting automotive grade... Just batteries for my golf cart that work as they should. 90+% of these cells are chinese made... Your dealing with china on some level regardless whether you pay a broker in the states to be the middleman or not. I'm not saying it cant have advantages but if your paying 50% more for the brokers cut is it really worth it? I guess its depends on the situation and if this is a reoccurring business thing.

Ive purchased about a half a dozen things from alibaba but they were mostly very expensive items made in china and normally rebranded here before being resold. I made one purchase for my business which was like 8,500 with customs and taxes and such vs the quote I got from the "reputable" company stateside that buys from that same manufacturer... The stateside vendor would have been over $16 grand with shipping with a longer wait... Now days the markup norms are no longer the 30% they used to be.

look at some brands of chinese BMS... literally over twice the price as others when rebranded by a stateside vendor for "support"

Exactly... people dont even agree on the US sellers being reputable..
Hey if you're in Australia and it's a different market dynamic I respect that. I imagine you guys have faster and cheaper shipping from China and more expensive domestic resellers. And it's probably annoying when Americans jump in and offer the American advice to not order direct from China when it's not as applicable in your market.

But don't think your advice applies globally either. Small Ali orders in the US can run into months of shipping delays, product damage en route with middle carriers that are unknown and uncontactable, and difficult recourse from the seller. All for very little savings, maybe 10-20%. Our resellers are very competitive with our direct Ali options.

I'm in the states... all the new cells stateside im seeing are more than 10-20% more on average, especially when factoring in shipping.
Ive bought from multiple stateside as well al ali vendors... All have been postive experiences.
Ive yet to find the 86ah CATL cells I bought for about $35 each shipped with tax anywhere near that from a stateside vendor.

I see thread after thread here about various vendors and people being disappointed in thier purchases and the majority of these threads are based off of the same bigger vendors.

lets take the common 105ah eve cells, docan has them for $880 for 16 cells shipped + tax.


18650stores price is the same, +and extra $90 for shipping so $970+tax..

aliexpress sellers have these from between $500 and 650 depending on seller.


now thats over a 30 to 40% price difference unless im missing something?

now if I were to buy 105ah cells right now? id buy them here because Ive bought here a few times now and everything has always been as advertised. but these are not "typical" US prices

Well, I wasn't theoretically opposed to it, I've always been satisfied with my aliexpress orders for electronics. But I saw the Docan relasered cells and they were off my list.

I think the bottom has dropped out of the competition for 105's and you're probably right there but for 280's and 304's I didn't get the impression there is a compelling savings and I want a CLEAN reputation. Selling B's as B's is fine but relasering is intolerable.
 
That is good as long as you have matching qr codes, for extra safety peel back the black cover and make sure. I just hope they don't do the bs they did earlier where 1 person got grade A and the other got Grade B all depending on what type of buyer it was.
She sent me pictures of the actual batteries with my name tagged on them and QR codes she is sending me along with excel spreadsheet she sent me. That QR code look right I hope not re-lasered I did put this one code in a decoder it did pull it up online matched 280 EVE battery.

As long as you can do this for every cell from Docan then you are ok, but Docan does this where the will screw over 1 buyer and give legit to the other one.

So be cautious when dealing with docan and always make sure you get a test report.

example:

Lt. Dan got good cells with a test report from ezeal:

in the same thread,
zcskywire2 got sanded / re-lasered cells:

Both purchased around the same time.

So its clear they have access to both, I think they much rather sell the re-lasered ones but if they suspect the buyer is not a push over/gullible they will send the ones with legit codes & test report.

Personally I would avoid, but I agree you can get a good price, however, its a mess IMHO.

I read that thread like I said I'm risking $1200 when you compare the cost differences between US and China. If I find the QR's were re-lasered I will claim it to my credit card as fraud.
 
I think your codes are fine and you have a matching report, but you are not like the typical goggly eyed buyer, you did your research; can't say the same for 9/10 buyers (myself included when I first bought cells form xuba and basen).

But sure peel off the black cover, clean with alcohol and verify but I think you will be ok.
 
Hi Gents,

Received two battery banks from Amy Luyan, all going well, the battery is assembled and in operation, EVE 304 A grade .

Now looking for more DIY battery boxes and received a quote from Docan

Free gift RS485 USB adapter 2pcs
Free gift battery 50mm terminals *6pairs
DDP sea shipping cost is 2300USD

Amy's quote is a little more expensive but the main problem DIY boxes are not stackable and need to be made support.

96pcs grade A EVE 304AH cells—discount price $106/pcs, $106*96 = $10176
7pcs Seplos BMS with RS485 with CAN with bluetooth with screen--$180*7=$1260

With double holes terminals
Fully matched
With the test data of each cell from EVE
With updated to flexible copper busbars
With insulation sheets

 
Update:

I ordered from Amy Wan of Shenzhen Luyuan.

$116 USD per cell
$90 USD Shipping

With flexible busbars, bolts, cell separators.

Seems to be good value.

Happy so far.


Ordering from EVE is only a good option if you want a pallet of 40+

They directed me to a corporate forwarder for smaller shipments in the US, but this seemed too risky.

At least with Alibaba the transaction stays on the platform.
Hi,
Can I ask what size cells these were? I'm also in Australia and looking to buy 8 cells from Luyuan too.
Cheers
 
Newbie here, and haven't ordered from Alibaba. Doing more research. From what I picked up reading through, looks like Luyuan is the only trusted seller in Alibaba, so if luyuan says its grade A, then it is grade A = EV grade?

Never heard otherwise.

Luyuan is exactly as people have said, they deliver exactly what is promised and stand behind their products. They may not be the "cheapest" out there but it isn't a roll of the dice either.
 
See multiple posts about getting test reports.
Keep in mind that test reports are useless except for if you believe they are legit and want to see how your cells tested.
Any company that would go through the effort of making fake QR codes can easily make fake test reports.
 
Faked test reports are extremely easy to verify, simply email the test report to doris[dot]liu[at]evebattery.com I have yet to see anyone do it. They respond in 24 hours, I have verified:

luyuan reports
sunfunkits reports
ezeal reports
batteryhookup reports
and if someone can send me 18650batterystore report I can verify that as well but I have no doubt it will come up as legit.

If scammers start faking test reports they are just going to make it even worse for themselves, clearly these people are in desperation mode I see post form alibaba sellers frequently on the forums now. Please buy buy buy. No list it as grade B and price it accordingly.

Long time coming but glad it finally has.
