So, I bought my Mini 2 renewed from a DJI Authorized seller on Amazon two months ago. It came with 3 batteries. When I received it, I updated the firmware through the app. Only problem was the battery only went to 70% on it's update and stayed there (failed). So, I put the second battery into the drone and tried it. It updated without a hitch. I then tried the third battery but no luck. I read a work around here and grabbed DJI Assistand 2 (Consumer Drone Series), made the appropriate changes in the defaultsettings.ini file and tried the 2 failed update batteries there. One updated with no problem. The other stalled immediately. Per the data I get on Airdata.com, the manufacture date on the failed update battery is 20-Jul-2022, so I wasn't concerned that it had very old firmware, and I currently have about 27 recharges through it with no problem.
I wanted a couple more batteries, just because. So I ordered them from the same seller, but through eBay this time. The app calls for them to be updated, but neither will update no matter what I try.
What have I tried you ask? :p
1. Multiple times through the DJI Fly app, where any of the 3 stall at 70% every single time.
2. Multiple times using two different Windows 10 computers.
3. 5 different USB cables which all transfer data without a problem on other devices.
The reason for my post is that, though both batteries had 0 times charged on arrival here, the dates on them are 31-Jan-2021 and 07-Jan-2021. So I'm a little more concerned about the firmware not being up to snuff. If only there were a way to check the firmware on the batteries, eh?...
Anyway, 2 out of 5 batteries updating doesn't lend much confidence. But,it almost seems ludicrous that I have 3 batteries that won't update without my seeing a TON of posts about the same issue here. So, is the issue on my end? I've read as many threads on this as I can find (not only here but elsewhere on the internet as well). I'm just not finding anything else to try (and yes, I have a clue when it comes to computers).
What else do I try? TIA!
