But prices have fallen sharply in recent years, and may continue on down. 2016 is two generations back, in battery years.

Probably future decreases will come from better power density, requiring less physical material for a given capacity, as demand for materials soars. It is remarkable how little lithium there is in a typical Tesla.

This is the bamboozle argument that Tesla's been pushing since 2013 model S, while hiding the true cost with the warranty.

A decade later, replacement pack for that car still runs you ~$20k, which makes model S cars disposable when they roll off the subsidized warranty.

Battery cost per unit of energy stored has fallen very fast for years.

What Tesla charges to replace batteries is a whole other matter. They charge what they think they can get.
