??? What ARE you trying to say. Did you read this?
Well just as a general statement one wouldn't normally want or need to supply regulated DC voltage to motors running at 14.4V/85A, but rather just power them directly from lead acid or Li-Po battery packs via a suitably rated motor controller. Then all the other electronics requiring regulated DC would be powered via switching regulator modules that would also use the raw 14.4vdc as their input voltage.

Yes that would make a lot more sense wouldn't it... I don't suppose there is a board that already combines a voltage regulator for the control circuit and the speed controller/relays for the brushed motors in one is there?
... this response was from the OP...
