The irony is a battery cannot STAY at any voltage for long and as the voltage lowers the current requirement becomes harder to fulfill. The LiFePo will stay above 12 volts for far longer than the AGM if the graphs are to be believed. One must assume that the amperage will remain as constant as the voltage and in proportion.
At the start of a listening session the meter shows 12.4 volts - the load toggles between 580 and 600 watts. Last night I went down to 11.4 volts before turning off the amplifiers. About two hours and twenty minutes. I am letting the voltage sink lower and it does not seem to harm anything.
The LiFePo batteries will be here Monday and it will be interesting to see what happens; hope my expectations are fulfilled.
I thought through the process as you have and that is why I though the AGM batteries would work. Only thing i can figure is the fact that the load is constant - no lessening or varying of the load - could this affect the battery's ability to continue to deliver 50 amps for as long as the ratings would suggest? Of course, both battery types will be affected but it seems the ability of the LiFePo to stay in the 12 volts range longer than the AGM is the key.
