DJI Battery can be automatically auto-detected from the log file. Here is some tips if you have problem to set it right on your inventory.
First, DJI log doesn’t report battery identifier consistently across models, and DJI manages 2 different serial numbers:

• The Printed Serial number: is the one displays on your battery itself (barcode).
• The Internal Serial number: this one can not be found directly. It’s written in the log file, for some model (inspire by example).

When DroneLogbook imports a log and can not autodetect the battery from your inventory, the imported flight notes contains some information about battery identifiers read on the logs ( remark: the drone name is also indicated there to auto-detect it as well).
Some example of notes:
“The Battery Printed Serial# from the log file is: A222B444. Set on your battery inventory to detect automatically the Battery in future log import.”
“The Battery Printed Serial# from the log file is: DEFF7888. The Battery Internal Serial# from the log file is: 111/456. Set on your battery inventory to detect automatically the Battery in future log import.”

Now you have to reflect these indicated serial numbers on your DroneLogbook battery inventory.
2 cases:

1. The Printed Serial number written in the Notes is the one you can read on your battery (barcode): set it in the “Serial# (Printed)” of  the battery detail screen:
   
2. The Printed Serial number written in the Notes does NOT correspond to your battery barcode: in this case, in the inventory battery detail screen, keep the barcode serial value in the “Printed Serial#”, and set in the “Serial# (internal)” with the number indicated in the imported flight notes, “internal serial number”:
