So, you've dropped from 178V to 171-173 during the same charge with no change in ambient temperature?

Access the pack fan exhaust behind the passenger side trunk lining. It should be no more than slightly warm.

In any case, I would terminate charge. A drop that low is indicative of inadequate cooling and/or cell failure.

There is a 14 pin (or so) yellow connector between the orange cable coming from the battery to the MCM. You can probe that connector without unplugging it and measure 10 stick pairs. If there is significant deviation in those voltages, you can conclude you have a failed pack.

BTW... Did you have a P1433 IMA fault?
