They should go to really old technology for trucks.

Iron Edison batteries.

They get better with age, can't be damaged by over or under charge and have been proven for over 100 years.

I have wondered why these are not used in offgrid solar applications.

But maybe they are?

They charge VERY slowly and would increase the car weight by several thousand pounds.
