Sam the Electric Viking tells us in this 9 min. YouTube video. Tony Seba (RethinkX) predicted EV battery prices would fall 50% by 2027. It now looks like it may happen this year. Last year they reduced prices by 30%. This is important because 35 to 40% of the cost of the EV is the battery. If the cost of the battery drops by half, it will make a major difference in the cost of the EV.
