2. You have low line resistance of about 0.4V/55A = 7.3 mohm. That's really low! Your typical cabling could have over 20 mohm resistance.
I suspect there is a little more resistance, that 0.4V drop was in the first ~10" of wire. The rest of the wire is significantly larger thou.
Once I move my source wire for the voltmeter closer the batt's I can recheck it, not sure when that will be. It's a TIGHT SOB to get into that area.
More resistance will lower the time the converter spends at rated amps as the voltage the converter sees will be a bit higher, but at least it holds until the converter is seeing 14.47. It should do the same for any battery or wiring.
