VNSZNR on Amazon 90Ah sold as 105Ah

[perryg114]

Here is the link to what I bought https://www.amazon.com/gp/product/B09TDKWBT7/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&th=1

The question is did I get what I paid for or is this a bait and switch. I will do a capacity test soon and let you know what I find.

Ok so I made my first battery purchase from VNSZNR on Amazon. Needed 100Ah with a 1C continuous rate with 3C impulse rate. The plan is to use some for solar RV power and some for a 48V system to power an EV. So I get them in and they are all within .1V of each other and I start looking at the QR codes. The codes say the battery is an LF90K nominal 90Ah battery not 105Ah. I believe there is a newer version of this battery called an LF105K but not 100% sure. I have
Attached is one of the QR codes that says.

Same thing happened to me, but on Aliexpress.
I know that ordering cells on Aliexpress is a gamble, but I took my precautions.

Advertised as a no-name 105Ah cell, I was expecting maybe used / grade B 105Ah cells:


The pictures actually look like EVE 105AH cells, but again I was prepared to be somewhat disappointed.

Well, the cells arrived recently, well packaged, no damage, no swelling. That was a good surprise as many sellers on Aliexpress are one big scam.



When I checked the QR code, I was surprised that these are genuine EVE cells, but disappointed that they are only 90Ah.

Of course I did a capacity test and got 91Ah. I opened a dispute, but the seller said that I should have discharged to 2.0v (big No-No... it will ruin the cells and there isn't much capacity anyways between 2.5v and 2.0v).
I request a 15% refund, for the 15% capacity difference.

Seller actually admitted that the cells are 96Ah, and that he is willing to give a lower refund.
Aliexpress stepped in and wanted more proof, but I really didn't have the patience to do more testing.
So I ended up approving a lower refund.
That's just because these are pretty nice cells, look new and are actually EVE brand.
If they were used, or unbranded, I would probably be more assertive.
ALSO, the LF90k are stepped to more cycles than the LF105. I don't think they have a K model for the 105, so they are 3000 cycles, as opposed to 5-6000 for the LF90K.

I guess maybe EVE had a big stock of LF90K that they needed to get rid of, and these resellers jumped on the boat.

In the end, I ended paying a fair price for LF90K cells, as sold elsewhere.

See my post describing this order:

The perfect Aliexpress Lifepo4 order... Well, almost.

If anyone has been following my posts lately, I've been complaining on how hard it is to get Lifepo4 cells here in the Middle East. While it's pretty easy to get smaller cells online, like Topband 25Ah, or some no-name 13Ah cells, it's a real hassle trying to get the larger cells. I've been...

Thanks for the confirmation on that. Buyer beware. What did you end up paying per cell after all was said and done? Mine were not cheap since I paid Amazon prices. I will probably return them. I just tested mine and got 92Ah at a .3C rate.
