Would these reading give me a bad cell error?

I got a error saying I had a bad cell. Also, RTH did not work. The battery does not look bad to me, but I really don't know any thing about them. I did leave the battery on when I charged it to get 100%.

I wonder if I may have a problem.

There is nothing wrong with those cell voltages. Maybe you stressed the battery out (e.g. strong thrust) towards the end of the flight?

Also, RTH did not work.

Did you hold the RTH button 3 seconds to initiate, and it didn't respond? Or did you try to click the GO app button for RTH?

Button on the controller. No problem with the other controller using RTH. I'll test it again tomorrow in the back yard, in the snow.
