If I recall correctly there are seperate parameters in the IBS system for regular lead acid then for AGM batteries.
The advantage of AGM batteries being their ability to withstand much faster charge rates than the old lead acid.
I would recommend ensuring the IBS is coded to the AGM and not still in lead acid mode via NSExpert.
Or disconnect the IBS as a more ghetto solution until you can have a decent indy code I your nice AGM battery.
