OK guys...huge news...I asked Basen for clarification on what they shipped me. I have to say that Basen has been very communicative throughout the process. What happened next astounded me.
1. I am being told these batteries are identified on the QRC properly as what they are, LF280 model, not N, K, or alphabet soup. She provided a spec sheet for the LF280. Shows they were designed in 3/18, but she says they were made 6/24/21.
2. She said the date code is no longer interpretable. I suspect EVE knows what the code interprets to, but is not made public.
3. drum roll.....to further prove what she says I was sent, she sent me a section of a spreadsheet including the cell I had given her the QRC for.
She shared this section of the spreadsheet with the arrow pointing to the cell I had given her the QRC for. The header is in Chinese, so you brainiacs can figure out what the other columns tell us. I assume the first column is the amperage, i.e. 291.9221. She says this spreadsheet is straight from EVE, presumably provided with the shipment.
4, The boxes were labeled XX/100. She gave me the FULL spreadsheet which shows the complete order was for 2000 cells. So, Basen bought 2000 cells, and then tested and repackaged 200 of them and sent them to the CA warehouse. The labeling on all of the boxes shows them being XX/100.
You can see the consistency in the cells based on actual EVE testing.
Has any other supplier provided the actual mfg testing data? I haven't seen anything like this before, but then I am a newbie.
I wish the sales people had accurate data on what they were selling. There has been a lot of consternation on my part due to the confusion on what I thought I was going to get vs. what I did get.
So, for whatever value it is, that is the current state of the world, as it turns.
