Basically think of it like this, no matter which way you configure the packs, the total available energy stays the same. If you are drawing the same amt of power, the runtime has to be the same (ignoring eff losses.)
Ie
1s6P : 3.7v, 12000mah
6s1P: 22.2v, 2000mah
Both equal 44.4 Wh (watt hours: Amp Hours*volts)
If you draw 4.4Ah/min for your run, you end up with 10mins no matter what.

+1. But I assume you meant 4.4
Wh/min (bold above).
Anyway, even though the 6s1p and 1s6p configs have the same Wh value, running the higher voltage on a low kv motor will be more efficient. High currents create heat, which in turns to voltage drops, which means more power is being eaten up as heat for nothing. (This last part is to the OP, not you Finn)
