I am a still small voice of calm and reason.

We can argue about this all day. Fact of the matter is, if they done their homework and matched capacity on the modules it will last a good enough amount of time.The Prius doesn't have to fast charge, and I'm not to what extent its BMU balances its cells, and what tolerances the BMU allows. As for the old modules, they get recycled and put into new products, and some probably even go into Powerwalls. The real issue here is that all of the modules in a pack were manufactured around the same time and if there were any manufacturing defects that caused 2 of those modules to fail, the rest are probably close to failure as well because they've all been subjected to the same operating conditions over their lifetimes. If I see any cracking in my tire sidewalls, ALL of the tires get replaced immediately, regardless of how they look, for the same reason. I'm not going to risk a blowout over trying to extend the life of my existing tires and trying to avoid having someone manufacture new ones.
