    Attached a video of my results from Dr. Prius. Are voltage spikes in the 19v area normal under hard braking? Also was a little concerned when the pack voltage spiked too. It shows I have 56 percent life left on the battery, I’m assuming these results confirm it’s about time to replace?

    that's about the average replacement years and mileage from what i've read.

    still, i wouldn't do anything but research until you get trouble lights. it could last for years.

    What is the voltage difference when the state of charge is low? right before the ICE turns on.
