Do batteries lose voltage as they''re used up?
The open circuit voltage goes down and the internal resistance goes up. Note that open circuit voltage is specifically measuring just the voltage the battery puts out with the internal resistance taken out of the equation. That is because there is no current thru that resistance, hence no voltage drop across it.
Lithium Batteries and Tow vehicle
As pointed out the typical truck will not put out the high enough voltage for a Lithium battery to demand full charge current. If the battery tried to draw large current the voltage drop in the cable will make the voltage it sees even lower (at 20A a #10 wire sees 0.95V drop over 20'') thus lowering the current it would want to draw.
