Thanks. This is the first for me.
It didn’t do it automatically for me. The app was telling me to do a battery update and one of my TB 48 batteries. The only way I could do it was downloading the firmware update on the SD card. My new battery I had just purchased is not asking for a update through the app. So I am assuming it doesn’t need it. I did save the firmware update on the SD card so if I need to do an update it’s already downloaded on the SD cardIt all happens automatically when you power up a battery that needs the upgrade ... only flickering lights will tell you it is happening ...
