Has anyone else noticed that as of maybe Sunday 1/15, that when the battery percentage hits around 45% or so the max motor power begins to be reduced. Ie on mine it went down to 95% and continues to decrease as the battery goes lower. Cycling on and off does nothing. Once it's charged again, it goes back to 100% power.

Update: Well I guess I must have missed it all this time, I swear it always said 100% before, even though I did notice lower acceleration when miles got down to like 20 left.

Completely normal. Low battery and cold weather will reduce available power.

But I've never seen the graphic on the instrument cluster showing a reduction of power for the motors. Unless Ford was doing it the whole time and not displaying it.

I see it all the time after my truck sits in the cold for 12 hours while at work.

This was my truck last Saturday, freezing, 8% SOC, 55% power limitation to the motors.
I almost never see this limiter except when it is cold and my SOC is under 50%.

I just don't ever remember seeing it until a couple days ago. I was getting limited with 41 degrees out, seems like overkill.
