Josh, The charger/alternator will start the charging at the higher voltage (14.4 ) and only begins to ramp it down when the acceptance of the batteries reduces the current requirements according to the programmed profile. With a voltmeter you will see it start at that voltage almost without regard to the current voltage of the combined batteries. With a charging source turned on you cannot determine the charge state of the batteries although the you could infer some status by the ammeter current measurement. Thus within moments of charging starting the ACR will close ... And with a relay all the batteries see the voltage and, of some concern, possibly high current. Both echocharge and duocharge limit the output current and voltage subject to the available inputs.
