I was watching a pod cast from EV TV and they were talking about how important it is to bottom balance a battery pack. I guess I don't understand the importance of lowering all of the cells to the same value before charging. Do these cells have some kind of memory? I mean if you lower them to the same value then charge them all to the same value what possible difference would it make. How would "they know" if you had not bottom balanced them to begin with?
