On my battery spec sheet it says (energy-1536 watt hours) but that really doesn't matter to me because I prefer knowing the amp hours over the watt hours,makes it easier for us dummies..lol
Right. 1536/12.8 = 120AH but that 12.8 is "nominal" so you need the "real" voltage to get the "real" AH and the AHs could be any darned thing!
Eg, if 13.6v is "full", then 1536/13.6 = 113AH
So if you had a Trimetric monitor that wants your "AH capacity when full" to be entered so it can keep track from there, you would enter 113, not that 120. Not a clue what your smart shunt wants!
You can fight that out with your monitors and meters, but it has to be tough being an AH man in that strange world. Rather you than me! :)
