The most ghetto thing you can do is use diodes and resistors across the terminals, but I feel like these days when you can get inductive active balance circuits for 10 dollars, you might as well do it properly.

And yea I think not pushing close to the max voltage is a good idea. 6 in series leaves some comfortable margin which should help the electrolyte last longer.
I bought a 4s balance board that moves high charge to the lower cell for my LiFePO4 battery. It kicks on whenever the voltage differential exceeds 0.1v.

I inquired about this balance board to see if it would work for ultracaps, but apparently not. I'm not finding anything else except the boards I posted above.
