> I wonder if these arguments take into account decreased battery life with a smaller battery in a plug in hybrid. I would think that it would be primarily a function of how much of the battery is treated as a 'reserve'. If you have 10-20% set aside that is not "useable", regardless of total capacity, then you could get similar cycles. There's also the possibility for using super-caps taking some of the brunt for high discharge (2-4s) events which could help with longevity. How expensive are they for these type of use case?
