Measuring V loss during charging
I know that a discharged battery can pull down the voltage at the charger. I was trying to measure voltage loss in my converter wiring, switches, etc. The two 105 AH batteries were 12.13v prior to ...

The charger's voltage has to be higher than the battery's or there would be no current. There also has to be some R or there would be no current. I don't know if the higher charger voltage is from voltage drop or if it is itself a real amount. A charger does seem to have a voltage rating like 14.8v but is that "real?"
I see lots of voltage drop as difference between charger and battery when the amps are high. The difference shrinks as amps taper. I don't know how much higher in voltage the charger "really is" out of that or if it is even correct to think like that.
