It is Ford's crazy charging system, BMS. My truck sits for days at a time and I have a Noco 5 connected when it is in the garage. I even have changed out the OEM battery from a H6 to a H7. I don't get the low battery warning but still put the Noco 5 maintainer on.That’s what the dealer said , duh ! Great fix
Mine is hooked up just like yours. I think by not driving it for three weeks triggered the message.Same here. I have the Noco Gen5X1 on the truck whenever it's parked and I don't drive for 3 - 4 days. I haven't had any issues since I used the Noco on my OEM H6 battery. (Same setup on my wife's 2024 Escape with H6 battery.)
I have attached to the positive behind the BMS sensor and to the body ground.
