By keeping the cabin locked, less stuff is powered-up and when I shut (not lock) the cargo doors the cargo lights only stay on for a few seconds.
Without locking the cabin the battery can flatten on about 5 hours if I'm in and out of the cargo area whilst on-site.

I've been pondering the BCM theory myself, and came to the same conclusion, as it powers up every time you unlock the van, and this in turn powers up several circuits which stay live for up to half an hour every time. I need to set up an ammeter in the battery feed, (which I can see through the window), and check to see how much power is draining, and for how long

Yes, you can change the target charge level in ForScan. IIRC by default the "smart" alternator target charge level is only 80 %.

Also my van has start/stop, this is automatically ON, The button is the A in the circle. I was thinking this was Eco Mode but now think Eco Mode is different, My start/stop button does not appear to change anything but the start stop function. Any ideas on this? Thanks

I'm using only the dual AGM batteries with a solar panel connected to the batteries via a Victron solar controller.
I have set the charging target to 100 % in ForScan and the alternator seems to work like a conventional one, keeping the charging voltage between 14,4–14,8 V.
The setting is ForScan was a wee bit confusing regarding the voltage. Not sure what they mean with "16V" there, the charging voltage tops at 14,8V like it should with AGM.

Have you read that?
Turning off Stop/start should disable Smart Regenerative Charging, but you have to switch it every time.
There are several other ways to disable SRC described in the manual:
- the High Specification Vehicle Interface Connector (A608) with a link.
- using the standard 8 way Vehicle Interface Connector in the drivers seat pedestal (link pins 1 and 3)
a wiring kit is available to plug into the existing connector
- Ford Programmable Battery Guard (A540) the process for retrofitting this is shown in the manual
