Flying Mavic 2 Pro with a Smart controller - battery issues.

[peikko]

While I am flying the Smart Controller gives me the prosentage of the battery OF THE BIRD on the top left corner.
Is there a way I can see the prosentage of the Smart controllers battery while flying ?

How can I check the condition ( not the charging prosentage ) of my Mavics batteries AND the condition of my Smart Controllers battery ?

My batteries have been acting strange lately and I try to figure out what is going on before I open my smart controller. First it only charged up to 56 % but now it seems to charge full again...
I did not fly for few months and after that the batteries started acting strange ( both - Smart Controller and Mavic 2 pro. )
One of the birds batteries is clearly swollen and I am not using it anymore.

I´ve been obviously Googleing the issues, but it would be good to hear your thoughts on this.
