That factory wire (~18 AWG) at 10 feet (who knows how long it really is) at 15A, voltage will drop ~2.0 volts. 18AWG at 15A will drop 0.2 volts per foot.

The voltage drop issue was hit or miss anyway, so the fact that you are improving it at least 1.5V at full load, that extra 0.2V won’t make a difference in this case.
