Hi,
Would you agree, repetitive charge discharge circuits, can, in some circumstances, need balancing circuits across each cap.
Considering three supercaps in series.

From the app note FvM linked... Just an FYI, not sure if your application is "super" caps

Passive voltage balancing is only recommended for applications that
don’t regularly charge and discharge the supercapacitor and that can
tolerate the additional load current of the balancing resis-tors. It is
suggested that the balancing resistors be selected to give additional
current flow of at least 50 times the worst-case supercapacitor
leakage current (3.3 kΩ to 22 kΩ depending on maximum operating
temperature). Although higher values of balancing resistor will work
in most cases they are unlikely to provide adequate protection when
significantly mismatched parts are connected in series.
