How big is the cable and what direction does it need to go in? Maybe you could make a groove in the alloy section so it exits along the side of the bars.
Very thin- two (I don't know the term for their diameter) battery cables for a 7.4V battery, formed into one cable inside a thin sheath.
"Cable" sounds a bit big- they are wires, thinking about it.
My concern would be that a groove might induce flex, which might induce creaking, which would drive me mad, very quickly.
90% sold on going in through the (metal) BB shell, up the seat-tube and connect to an in-seatpost battery.
