The BMS is not the same as the vehicles under 8500GVW that are subject to CAFE restrictions. These trucks do have BMS and it is not talked about in the manual because it is not a repair as it's all software based and done through the BCM.
The BMS system is different then the F-150 and other vehicles as these trucks are not subject to CAFE restrictions. The BMS is shown on the forscan spreadsheet.

The Bluetooth started working on the laptop so I connected to Forscan and now have some questions. Where can the battery life be found? Just to verify the reset. Also, where are you making the change to AGM? Bellow is what I am seeing in the BCM.

Second replacement set from ford installed in January 2021 at 35k miles. Removed last week at 48k.

That is what many use. I use a light coat of Vaseline instead. Not sure if anything is really necessary when using AGM batteries, the only time I have ever had any corrosion was with non AGM batteries.

What *should* change between a lead and a AGM battery is the charging profile, the AGM will work better getting a higher voltage charging up and floating. This is most important when you have a “deep discharge” AGM battery but it’s also useful for normal car batteries. I guess that the Forscan adjustment will change the profile…

Actually AGM requires lower voltage than flooded cell type batteries. Look at your chart - it's right there.
What happens when you charge an AGM battery at the flooded settings? It will gas and eventually fail.
