Quality caps are closely matched so they don't drift very much. The fact that higher voltages exponentially increase leakage means they self-balance.
I'd do the initial charge with them in parallel to 2.25v, but after that they should be fine.

Charging from fully discahrged caps one can reach 2.7 while another is at 2.0V

Keyword- cheapo Chinese. I've heard many people report receiving defective caps, but quality ones should contain no defective units, and be closely matched. I've not had a single bad one out of 17 so far.
That said, I did wire up LED balancing because it's so cheap, and I was paranoid, and it's an easy way to visually see state of charge for each cap.
