Maybe I missed it but do you know which model they are selling? As you know someone was selling EVE's in the batteries for sales section of the forum and it turned out he was selling LF280K EVEs. And the cells came from Basen.
I think the ones that were coming from China were N but I don't think we nailed down what these were. The story, take it for what it's worth, was that they got a shipment in (China) and immediately dispatched a portion of that inventory to the US for people like me who don't want to wait.
Someone contended that there were batteries as old as 2019 out there and being sold as new. When I asked about it, she said:
"The goods in the overseas warehouse were produced in June this year, and EVE 280AH is very popular. It is impossible for the goods of last year to be sold this year, and EVE 280AH has been out of stock from March to July this year"
From that I take it that they are buying from EVE, EVE was out, and then EVE made batteries in June which these are supposed to be.
She then said:
"The goods were shipped from China to the United States at the end of June and arrived at the overseas warehouse in mid-August"
Made by EVE in June, obtained by Basen and shipped to the US in June, arrived in August and now will be at my house in two days. That is pretty darned quick if they shipped end of June and were in their warehouse mid-August...basically 6-7 weeks.
Regarding the other batteries being sold, and I assume you mean the individual, were sold as Basen and sleuthed to be EVE 280 K. It happens that I asked them about those batteries, not mentioning who the seller here was, and they said they did come from them, but from a batch that they no longer had. They made no connection between that batch and what they are getting now.
BTW, someone said the 3-digit code on the QR label was a date code, but no one knew how to interpret it. She said the date is not on the QR label.
