Any alternator, no matter the control, just attempts to maintain voltage at the output. Where the power goes the alternator does not know or care. Jumper cables are fine but will be expensive and bulky if the wire is thick enough (#2)to minimize voltage drop.

The upgrade in the video is not going to help.
