Ideally there should be none.
However, in practice, and we'll presume you are referencing the voltage
required to operate a 12 volt DC 100 watt transceiver, then 0.1 to 0.2 volts
would normally be acceptable. This is about 1% {13.8 * 1% = 0.138} If
every thing operates in a straight line fashion, then the output of the
radio would not be 100 watts but less 10% or 90 watts. Then we get into the
dynamic regulation caused by the changing load due to CW or voice peaks.
Short power leads, good power supply regulation and #12 wire for runs of 6
ft or less work quite well. Be sure all terminals are soldered and not just
crimped. Makes for lower IR loss.
