Reading on Dr Prius App when slowing and applying brake

I own a 2007 Prius with 368,000 miles on it. I put a Hybrid Replacement Battery in the car in April of 2021 from a company based out of Atlanta, Ga. This replacement Hybrid battery lasted for about 14 months, and I was getting these readings in RED about a month before this Hybrid battery through a P3000 code. The Red Triangle of death is lit up on the dash. The Dr. Prius app now says that Cell #9 is bad.

These readings from the Dr. Prius app came up from time to time especially, when the car was in "Drive" and slowing down, I was going down a hill, and applying the brakes, especially when I was applying the brakes. This is when the system is charging the battery.

Is this a sign of a bad inverter?

I have not taken the car to be scanned by the ToyotaTech Software, but plan on getting it checked before putting another hybrid battery into the car.
