how can i upgrade my 2nd battery firmware for phantom 3 standard

I have the same question, but for the Inspire.

I did the upgrade to 1.4 but only the battery that was installed during the upgrade has upgraded. The app shows the message "battery upgrade required" with my 2nd and 3rd batteries and I have no idea how to initiate it (I have tried leaving the .bin file in the sd but nothing happens).

Furthermore when the non-upgraded batteries are installed in the Inspire, looking in the menu "About" to the Aircraft Firmware Version I see the old one. As if the aircraft  itself was not upgraded.

Please help

Solved.

It was sufficient to redo the upgrade with each battery (I had not the correct .bin in the SD).
