Seems like All sellers of LiFePo4 cells claim “A+ New” ... or claim nothing at all ?? So are you Really getting “New” cells and are they Really “A+” and how do you Know when you buy ?? If someone advertised “B- Really CRAPPY Cells” then I probably wouldn’t buy those !! ? But nobody says that !!
So, I recently bought 4 “New A+” 280ah cells and when they arrived they looked good ( except for the one that seemed a bit Bloated ) well packed and clean, so I balanced them and put them to work with an Overkill BMS !! They wouldn’t stay balanced, one of them ran Wild charging and discharging and was determined it was a bad cell ( wasn’t the Bloated one ... I know you were thinking that ) so ordered a Replacement “A+ New” cell and pack still won’t stay balanced and Another one seems to be a bit Suspect !!
So - how do you Know when someone really is selling good cells and when they aren’t ?? It’s not like you can ‘check them out’ first at your local Home Depot. I don’t know that it really matters Where you get them as everyone advertises the same wheather Amazon, AliExpress, EBay - they all say “New” or “A+” or similar, so ... how do you Know ???
I know you’re going to Ask so ... I got them from AliBaba, no idea what Brand they are there’s no indication on the cells - they do have serial number stickers by the vent and a generic white label on the side telling what they are - a 3.2v LiFePo4 280ah cell.
Questions that make you go ... hummmm !! ?
ps — how do you Dispose of a bad LiFePo4 cell ??
