Last time I tried to estimate that it seemed with a passenger car you get some win there that offsets the battery weight. Something around 300lbs. My guess is if batteries got 30% more power dense the weight penalty would disappear. Part of that is as the weight of battery drops you can make the rest of the car lighter as well.
