What effect does the lower voltage (per motor needs) have on the motor
performance ?

Here is a quote from the Gecko White Paper.

"Also note from the previous graph that motor output power doubles
when the power supply voltage is doubled for either series or
parallel-wired motors. Notice that a parallel-connected motor delivers
performance identical to a series-connected motor running at twice the
power supply voltage."
