Since we're on the subject....
I hate beating a dead horse as this has already been explained to me when I ask but I'm just not getting it completely.
I have considered adding the RV-2030 to my system, but still need to digest why I should.
Without the 2030, I'm relying on a Zantrex which I'm told gives percentages mostly based on voltage, and I'm told that's not accurate. Here's what I'm not understanding:
Using the attached SOC chart, at 12.1 volts I'm at 50% SOC. When the batteries were brand new, we could use math to calculate arrival at 50% SOC: when usage equals total capacity divided by two, you're empty. And at that point no-load voltage would read 12.1V. When the batteries age a little, it will take fewer AH usage to get to 50% SOC, but when we
do get there, no-load voltage will again read 12.1V. So, speaking very slowly, and using pictures instead of words where possible :
, how come my Zantrex doesn't already tell me what I need to know? (Perhaps write it in crayon too.)
