expected normal voltage drop from load?
Is there a rule of thumb or guidance for an expected voltage drop based on amp load on a pair of 6V GC batteries? I was tinkering in my trailer this weekend and ran a 750 watt AC electric heater off ...

"Now I understand that when a battery is up in absorption voltage range, the amps required to hold Absv keep tapering. If the amps do not taper then voltage will just keep rising"
This concept still bothers me. I don't believe the amps keep the voltage up.
The charger voltage is kept up by itself. The battery voltage is based on the SG of the electrolyte. The difference between the two voltages makes for amps across the R.
If the charger voltage is maintained amps will taper as battery voltage rises.
I don't think that if you somehow dropped the amps (by having a lower amp current-limit charger?) but kept charger voltage steady, that battery voltage would suddenly drop too. I think it would just rise more slowly from then on.
I think LY has the tail wagging the dog, but I could be missing something in all this.
