Electrical Battery problems blank screen

When you use your Battery Tender, are you connecting the negative to either the negative battery terminal or a chassis ground and connecting the positive lead directly to the Ford Battery Minder System rather than the positive battery terminal? It has to go through the BMS.

@RushMan which OBD2 Device do you have installed and working with your Torque Pro App?

Reason I ask is you may want to check the user manual or specs for your OBD2 Device for current draw while plugged into the vehicle. I have seen several products (e.g.Veepeak OBDCheck BLE+ Bluetooth 4.0 OBD II Scanner for iOS & Android) with enough current draw that the instructions say to not leave plugged in the vehicle for more than one week.

In your case the battery dropped from ~100% to 44% in 26 hours which is pretty fast but it’s possible your OBD2 Device (which probably is using Bluetooth) might be draining the battery.

I don't leave the Bluetooth OBD MX plugged in. Nothing plugged in to the USB or 12V outlets either.

I unlatch the hood, so that after the BS BL sits, I can check battery voltage without opening the driver's door to unlatch it (which would wake up a bunch of stuff).

How would locking it make a difference?

Supposedly, the BMS resets when the car is locked and undisturbed for 8 hours.

The Ford Maverick has the black screen issue with the instrument cluster, there is a recall for the Maverick. The Maverick is almost the same as the Sport, wondering if it's the same issue.
