100 amp charging source vs 2 grp31 AGM
My friend plans on running an obscene stereo in his new box on wheels acquisition. He wanted a dedicated power source for it able to power it for a respectable amount of time from battery power alo...

Would an amplifier need a certain voltage to operate? then whatever VA (or watts) it takes would determine how many amps that came to as a battery draw? No idea, just wondering. I think the Winegard antenna amplifier needs something in the 11-14volt range, but not sure about that either.
I suppose with some DC loads you would not need the battery there at all. I don't know what these outdoor sound systems with amplifiers need for input as volts to get their watts.
Yes the 14.8 should be maintained while charging in the Absorption Stage but the actual time to maintain that varies with battery bank size. The amps will taper during that time, so it is all about how long it takes for the amps to taper to the level that you would then shift down to a float voltage. Most automatic chargers seem to shut off or go to float at about 97% SOC on the battery.
For a power supply situation, AFAIK the converter will do its full rated amps on a battery bank at any voltage you like as long as the battery is being drawn at a higher amps rate than that. eg, my 7355 will do 56 amps at its fixed 13.8v when on a battery running an inverter when the inverter is pulling more than 56a (tested at 90 amps.)
