Wait a minute here. Maybe I'm reading something wrong, but for a given setup, a lower voltage will result in lower current (and lower speed). And since current draw is lower, ripple current and voltage drop will be less as well.

That is exactly my thinking. Now, if I go trying to gear it way up to match 4s speed, or something silly like that, then it would be a different story.
In any case, I found these if I need 'em...
