i've read something online
End Amps is a trigger used by the charge controller to determine that the battery bank is fully charged and no longer accepting current. It is important to properly program the End Amps setting at the time of install. If this is programmed incorrectly or incompatible with the battery type sulfation will develop quickly.
As a battery reaches full state of charge its charge acceptance drops considerably. Typically, when the charge current falls below 2-4% of the battery capacity for 60 minutes the battery bank is no longer accepting charge and the Absorption phase should be terminated. Flooded batteries have a higher internal resistance, so we recommend setting End Amps at 2%. VRLA batteries, such as AGM & GEL, have a lower internal resistance. For these models it is recommended that End Amps be programmed closer to 3-4%.
where in the quattro can i setup the end amps to go from absorption to float mode?
Or how much is programmed in the quattro?
i see that on the shunt, but for what i know the quattro doesnt use that value and that value is just to auto sync the 100%
