where are you reading the voltage/amprage from?

Built-in display of Renogy controller.
Purists here could point out (rightly so) that voltage should be measured on the battery, but my cables to battery are short and currents are low so there is no issue with voltage drop.
There was also voltage measured on the load in this particular case - fridge display - it is of course lower than the one on the Renogy.
Note that while Renogy voltage settings are in the Battery Parameter tab of the app - not in the Load Parameter, some of them actually control the Load terminals, like Over Discharge and Discharge Limit. It disconnects the Load terminals. Other voltages and settings are related to charging process.
