My post above was not meant as a joke, it was offered, free to use, as an alternative way to wire three batteries in a “balanced manner” as you like to say. I know that no two or three batteries are exactly the same but that is the assumption that is made every time someone on the forum talks about balanced manner. That is the assumption I will use here.
As MEXICOWANDERER offered it is time to introduce Mr. Kirchhoff. His laws I became friends with almost 50 years ago. If someone takes the time to do the analysis it will be found that the star configuration and the parallel link configuration are electrically the same, no difference.
The trick is to make the link from the + terminal of battery 1 to + terminal of battery 2 and the link from the – terminal of battery 2 to – terminal of battery 3 equal to on half the resistance of the other two links. This is done by putting two links in parallel.
Do the analysis!
