I would like to hear from the professional,

the cells are connected series. min voltage : 9.6v. max voltage : 12.6

what's the most effective and efficient of way of creating output of at least able to handle 3.3v(1A), 5v(2A), 12v(2A).

Can someone point me stage by stage because I am confused should I buck-boost 12v then to 5v then 3.3 etc. I want to get most efficient regulation
