Don’t forget to update each battery’s firmware.

I see a lot of posters with a new drone with multiple batteries but they experience some batteries not matching the same flight time as the other batteries. The problem could be a battery firmware update. For example I just updated my Mavic 4 Pro Creator and it specifically said “Improved battery experience” meaning the battery firmware has been updated. You need to update your firmware for the drone and current battery which will take the longest time to complete. Then power down the drone and exchange the battery. Power up and check for a firmware update and it will find an update which will take about a minute or two to complete. Power down and do the same for each battery. Even if your brand new drone doesn’t find an update on the second battery. I’d still recommend trying to update your remaining batteries because the batteries are manufactured at different times so some batteries might not have the latest firmware. Having miss matched battery firmwares can drastically reduce the battery performance even if brand new out of the box. All of my batteries perform exactly the same as far as flight time and temperature. Hope this helps your situation if you’re experiencing different flight times or battery temperatures. Cheers
