I created a circuit that involves a relay (or several. whichever you prefer to use)
You can also use transistors or mosfets instead of relays
that basically charges the capacitors or batteries in parallel when you go to charge them
and when you take them off of charge.
they are switched into being in series with each other

could be used with a charge pump circuit if you beefed up all the components.
And used transistors/mosfets instead of a relay. and also used a switching circuit with feedback to keep the output voltage constant
using mostly Sziklai paired transistors would be reasonably efficient too for switching the capacitors. with minimal losses
Depending how many capacitors you can use it as a boost charge pump circuit
The best thing about a charge pump circuit. is the output is completely separated from the input. and with this design with modifications and tweaks you can use it as boost or buck charge pump. depending on ratio of keeping the capacitors charged fuller or less full.
it should naturally keep the capacitors in balance by design. since it charges them all in parallel first.
You could get away with small or large capacitors depending on the switching frequency.
the duty cycle can be very low when there is no load attached and it keeps the voltage constant.
