I am pretty familiar with the appearance of the traction battery in the 1st, 2nd, and 3rd generation Prius. I've even changed out a few batteries on the 1st gen. But I've never even seen so much as a photo of the PHEV battery. I'm curious to see a comparison of the normal Prius battery and the Lithium pack used in the new Prius. Does anyone have a photo showing the two side-by-side?
