I'm pleased that Autel must be quietly starting to phase in battery and storage upgrade on the newer Elites When checking where the slot for the micro SD card is at I discovered my new Maxi Sys Elite actually has a larger capacity that reads 15400 mah inside where the specs list as a 13600 mah battery. (Zoom in on the picture)
Not so pleased I was unable to back up the scanfolder to a 32GB USB thumb drive after updating System Version to V3.65 and the LIB Com,
I was really happy ES Explorer , SD analyst showed the internal storage size to be 53.15GB, (instead of the listed 32GB). It showed 36 GB of available space before I did the 40 updates, and 17 Gb used so I don't think I need to worry about adding a micro SD card for awhile to fit the BMW updates for awhile.
