Some of the ones I purchased in May read 88C. I am not worried. At least @Mikey and I are in the same boat even even if our cells were not on the same vessel.
Those cells were purchase from Xuba.
The good news is if 87C was July 2018 then 88C has to be later than 2018.
NOTE: Subsequent investigation revealed that I also have some other cells that are 898 and others that are 88J. Those may be the ones I purchase from Deligreen. I also notice that the numbers are not sequential. After two months of runnning them in my pack and getting them all balanced as far as voltage I don't know what to do? I do have eight coming from Shenzhen Basen and maybe they will be 88C so I may disassemble my 2P16S pack, put the 88Cs with their brothers, then rebalance the entire pack. While I am at it I think I will reassemble them in sequential order which would make more sense.
Then if I have some with odd dates I can put them in the 4S packs I am putting together for PSPS events for my sister and daughter. If we do get this date issue resolved by then, should I give my 80 year old sister the older ones and give my 36 year old daughter the newer ones?
Any thoughts?
