Since you asked this and I replied here I had also updated our page that discusses batteries with a table now and it can be seen here: https://learn.ubiquityrobotics.com/need_to_know
This page if you have not seen it has had much of the info on battery selection and other things useful to know for Magni owners.
No we don’t have a breakdown in the form of detailed graphs.
I thank you for your question on this post because it is questions like these that constantly lead us to improve our documents on our Learn pages when I realize from questions like this post that we are lacking important documents to help customers better make decisions (in this case how big should I get my batteries).
If you do not have it bookmarked already, our Learn site is in fact our ‘Manual’ for both usage and support and expansion.
