It is not necessary to have $10,000 battery, use smaller battery. Audis/Mercedes/Porsche can justify their price's but $43,699-49,199 for Kona electric or Kia Niro $44,995-54,695 is not when you can purchase BMW i4 Gran Coupe $54,990 The 2022 ICE Kona starts at $21999 so there is no why it is worth $21700 more to make it electric.
On the other hand BMW 4 Series Coupe ICE starts at $53,650 compared to BMW i4 Gran Coupe $54,990.
