Very interesting....we first thought LF280 ended production in July. Then we just learned some of the batteries being sold now are December, 2020 production. Yours is the first EVE S/N I have seen with a 2021 "B" code. As an aside, the 32 after the B likely isn't March...There was a forum thread somewhere on here who said it was some hex code or ?? Batteries known to have been made in December were ACx codes so they had numbered from 0 to C.My first post. Been reading this forum and learning for some time now. Invaluable!
I too was trying to decipher my QR label - which led me to this thread. Attached a photo of the QR label from Eve cells I recently purchased on Ali Express (Sanben Global Battery Store). The date code is B32 - so I take that to mean 2021 March 2.
By the way, these cells indeed appear to be, as advertised by the seller, brand spanking new. The whole pack of 8 are perfectly flat (no bulging at all), and very well matched from what I can tell. They were also seemingly at exactly the same state of charge upon arrival, and almost perfect balanced - as I found out while top balancing them myself. I'm in the middle of a capacity test - I can only pull 5 amps so the test is a two day test - but that's okay. I have high hopes to see the full 280.
