No, I was including it. Adding 150 lbs to a 1,200 lb battery only reduces the overall energy density by 11%. Adding 360 lbs to a 120 lb tank of gas reduces energy density by 75%. Where gas originally appeared to have a density advantage of 20x, it's now down to a 6x advantage after factoring in powertrain weight. That is what I mean when I say that batteries are catching up if you consider the total weight of the system.
