          You WANT the parallel! by ideur2015-01-10 10:12:37
            A hint: by ideur 2015-01-11 02:49:40
all the heat generated in the linear voltage regulator is energy LOST and NOT available to feed the motor!

That means that you want a switching regulator. they can be up to 97% efficient!

A three phase "Buck converter" might be the medicine you look for. Wikipedia entry

OR:

Make 110% sure that you do NOT overcharge the battery (which you should do anyway!) and forget the regulator. Add some anti-parallel diodes to the power transistors (MOSFET) {cathode towards the positive} to suppress any spikes.

Good Luck
