All over 280AH, All Voltage/IR's match up as they should at the points. This will give you a consistent 280AH with the full Working Voltage Range of 2.900-3.400+ Remember: Max Voltage Range is 2.5000-3.650Vpc while Nominal Voltage is 3.200 and working is defined as 3.000-3.400. Above 3.475 and below 2.875 are the Voltage Cliffs that represent about 5-7% of "gross capacity".My order data from Amy. Grade A matched cells. new "k" cell. seems good to me , but Im not a expert...
ROFLMAO indeed. The EVE Auditor... what a notion. Pure Bilge.I've also inquired with Auditor at EVE to trace the serial numbers in question and advice of Specification # and Manufacturing Date.
Hi Amy - 5.6AH / 280AH = +/- %2.00 Probably a good idea to add this to the product specification pre-sales.I think I have explained it clearly to you, right? According to the matching standard of EVE, it is normal for the cell capacity difference in each group to be within 5.6AH.
This is the kind of information I do agree should be published voluntarily by the people you are buying from. BUT, as an educated, experienced consumer when someone says "matched" the first thing that should come to mind is "what does matched mean?", and then you ask that question.Hi Amy - 5.6AH / 280AH = +/- %2.00 Probably a good idea to add this to the product specification pre-sales.
First of all, I apologize deeply for some misunderstandings and unpleasantness caused to you by my work negligence.
1. About not replying in time:
Usually, after receiving customers' request for checking shipping, I will contact the logistics company immediately, but they usually do not reply to me in time, maybe two days, three days, or even a week. They may need to confirm the specific status of the order with their foreign agents, or they may be very busy. I will reply to customers only after I get their reply.
I receive many messages every day, and it is very likely that I missed some messages that did not respond in time. When the customer contacted me for the second time, I just found that I did not respond to his first message in time. This is my work negligence and fault, sorry again.Hope I could do better in future, thanks so much for all customers' understanding and tolerance!
2. About "66" and "71"
In fact, I really rarely pay attention to these serial numbers. I pay more attention to their test data, such as the capacity difference, the internal resistance difference, and the consistency of the voltage.
So, I was very confused when you mentioned these to me today. But I quickly understood the problem you mentioned.
I checked all the test data of the batteries ordered in the last six months from EVE, in fact, they are all "66", only July is "71" (if you need, I can provide screenshots of all the test data) I contacted EVE Sales, they replied:
This is exactly the same battery, just the serial number is different.
What you understand "66" is the specification code of the old version with M6 thread,and it is a product of 2019. This is inaccurate. About this, you could contact EVE directly. In fact, I also hope that you could contact EVE. , Their explanation will be more professional.
You can confirm with EVE:
(1) Does Lu Yuan order grade A batteries from EVE?
(2) Does Luyuan require EVE to match each batch of batteries, at first 16 batteries as a group, later 500pcs in a group.
(3) Is "66" only the specification code of the old version (with M6 thread)? Has it been discontinued after 2019?
(4) After receiving these batteries, please test them, I guarantee here: If they are not matched, Luyuan will take the responsibility!
3. For commercial batteries, yes, matching requires additional costs;
For real grade A batteries, it is included in the price.
4. About the price of EVE you mentioned is much higher, you could check that via their Alibaba store.
In fact, our profits are much less than you think. We just hope that more and more people can accept real grade A batteries.
If you have any other questions, you could contact me through Alibaba or here.
Kind regards,
Amy
Still wondering what makes them matched? not the Ah as that is from 288 to 292. It still makes me wonder what "matching" is going on as that just seems like a random list of cells. Of my last 8, all were 291 but a 289 and they are going to exchange it so they are all 291.My order data from Amy. Grade A matched cells. new "k" cell. seems good to me , but Im not a expert...
May I ask who 'They' is?Still wondering what makes them matched? not the Ah as that is from 288 to 292. It still makes me wonder what "matching" is going on as that just seems like a random list of cells. Of my last 8, all were 291 but a 289 and they are going to exchange it so they are all 291.
Have mentioned my last order was with Basen.May I ask who 'They' is?
So .... are you saying that Basen is going to guarantee matching the cells within a capacity of .36%?Have mentioned my last order was with Basen.
Second time you tried putting words in my mouth. I never said that, I don't represent Basen so I don't speak for them.So .... are you saying that Basen is going to guarantee matching the cells within a capacity of .36%?
You said that they are going to make sure they are all exactly 291 AH .... which is within 1 ah .... I just did the math for you.Second time you tried putting words in my mouth. I never said that, I don't represent Basen so I don't speak for them.
I didn't use the word "exactly"....do you always twist people's words to fit your own narrative? Secondly, what agreement I make with a vendor is between that vendor and me. You and everyone else should reach their own agreement with sales.You said that they are going to make sure they are all exactly 291 AH .... which is within 1 ah .... I just did the math for you.
Well .... You did say they were going to make sure they were all 191 AH.I didn't use the word "exactly"....do you always twist people's words to fit your own narrative? Secondly, what agreement I make with a vendor is between that vendor and me. You and everyone else should reach their own agreement with sales.
Even if I don't return and replace the 289ah cell, a spread of 289>291 is better than the 5 Ah spread others are getting, not to mention a mixture of model numbers.
As far as we know EVE stopped production of the LF280N and started production of the LF280K. I am not sure of the exact dates but the reply you received from Amy was the end of June according to your screenshot. When did Amy start selling the LF280K?
As far as what your pending order shows, clarification is needed from Amy. I don't know why N's and K's can't be mixed but the terminals on the K's are closer to the edge, and I think the K has a slightly higher height. I think EVE would be the best source to find out if the K and the N can be mixed.
Please keep us updated. It's great you are trying to get to the bottom of this so others can be cautious at this point. If paying a premium I sure want to know exactly what I am getting and expect matched cells by model number and capacity.
Lets relax a bit. You have implied you expect all of your cells to have 291ah capacity. To me it means you are implying you expect each of your cells to be exactly 291ah's capacity. Of course that's not possible. The replacement cell could be 291.003ah's capacity or 290.999ah's capacity.I didn't use the word "exactly"....do you always twist people's words to fit your own narrative?
You just made your agreement public. Thankyou for sharing. I think we can all learn from agreements others make with suppliers. Hopefully Basen will hold up their end of the agreement and you will receive cells that are all exactly 291ah's...lol.Secondly, what agreement I make with a vendor is between that vendor and me.

True and the mismatch of the model numbers concerns me more than the capacity mismatch.Even if I don't return and replace the 289ah cell, a spread of 289>291 is better than the 5 Ah spread others are getting, not to mention a mixture of model numbers.

I wonder if the capacity of each cell will drift a bit after the cells are run through a few cycles?
True and the mismatch of the model numbers concerns me more than the capacity mismatch.
Right but what I was getting at is if all the cells come with 291ah's capacity, and are run through a few cycles, will the capacity of the cells remain relatively close to each other? I know the capacity of all the cells will drop some.I've tested extensively, capacity drifts mainly with the temperature.
For sake of the discussion, when I say 291, I mean 291.000 to 291.999.Lets relax a bit. You have implied you expect all of your cells to have 291ah capacity. To me it means you are implying you expect each of your cells to be exactly 291ah's capacity. Of course that's not possible. The replacement cell could be 291.003ah's capacity or 290.999ah's capacity.
If you know the shipper has 180 291s and 20 of something else, it seems they could "match" the 291s and put the non-291s with other non-291s. It was just a commentary on what they could have easily done. Just saying..If I received 7 cells with 291ah capacity and 1 with 289ah capacity I would be elated. But that's me. Everyone has their own tolerances and expectations. I hope you will take the time to capacity test your cells. I wonder if the capacity of each cell will drift a bit after the cells are run through a few cycles?
Basen has already told me they would swap the cell. You guys make it sound unnecessary. BTW, my load tester came in today. I am charging the 289 to 3.65v and then will load test it. Due to my ineptness, you will likely hear me saying I blew something up.You just made your agreement public. Thankyou for sharing. I think we can all learn from agreements others make with suppliers. Hopefully Basen will hold up their end of the agreement and you will receive cells that are all exactly 291ah's...lol.
Glad we can agree on that part. At least I got all the same model number, date codes ACD-ACG, and within a couple Ah. With the 2.89 thrown in, my 8 cells have a spread of 2.63 Ah. Take that odd cell out, my spread is .63 Ah.True and the mismatch of the model numbers concerns me more than the capacity mismatch.
