I do think the AGM battery is partially depleted, it would only charge to 72% on my charger before it went into trickle/maintain mode. the LiPo battery was showinig 13.1 when I checked it out of the car. I'd be curious what the voltage shows on the AGM when the car is asleep.
I found this thread -
https://www.m3post.com/forums/showthread.php?t=1356590 Sounds awfully familiar and proves it is not outside the realm of possibilities the dealer tech did not follow proper procedure. I'm going to pull things out tomorrow and check over the wiring.
I spoke to the service manger of the dealership, he told me to bring the car back on Monday and they will go over the work and make sure it was done correctly, if it wasn't, they will fix it and let me know what was wrong, if it all checks out, they said they would give me a courtesy diagnosis which I told him I thought was fair...but I don't want to wait until monday and if I see something obvious, if I can, I'll just fix it myself.
