. . . I have 6g on an approx. 10' one way run between battery and converter. New converter will be a 45A model. A 1.5% drop will bring 14.6v down to 14.4v. Based on my limited knowledge, I'm thinking I'll have at least a 1.5% drop . . .
Based on the voltage drop calculator I'm using, a 10 ft (one-way) run of 6 awg at 45a will result in a .36v, 2.47% drop at 14.6v. This is best case and assumes all connections and terminals are properly tightened and crimped. Everyone has their own personal preference in terms of an acceptable voltage drop. We typically strive for less than 2%. YMMV.
