As is known to all,CATL deals with EV manufacturers or enormous ESS project only.
In the gold time of Lithium battery when CATL factory had not enough production capacity for EV demand,it's impossible to get Grade A+ catl battery.The one in market was that removed from EV,refurnished,used battyer,in which the best one was unqualified EV battery(Grade A).
Then you see 280ah,300ah,302ah,310ah,320ah CATL cells,it hardly distinguish what capacity battery it is due to same appearance and scratched QR code.
Some catl cells with small QR code that is not scratched.However it is not qualified HSEV(high speed electrical vehicle) battery.
This is EV grade CATL 280ah battery,with QR code(not scratched and changed),factory data supplied for inspection.
