GM advices not to charge more than 90%, and discharge less than 70 miles. So, effective range of 60 miles? Not much more than my 50 miles Leaf. At least, Leaf batteries don't catch on fire. Leaf batteries are inefficient but over-engineered. https://www.cnbc.com/2021/07/23/gm-issues-second-recall-of-chevy-bolt-evs-after-vehicles-catch-fire.html

Bolt EV owners reported they are not able to sell their cars even for very low prices due to the fire repercussions." They have a helluva problem on their hands. Sounds like another government bailout in the making. https://www.autoevolution.com/news/gm-tacitly-admits-bolt-ev-recall-is-not-enough-asks-owners-to-park-outside-165345.html

Anyone'd do better just buying a golf buggy. The technology just isn't there yet.

Anyone'd do better just buyitng a golf buggy. The technology just isn't there yet.If the price is right, perhaps around $10,000. I would buy a bolt. To be more precise, the estimated range is: Bolt: 40% (90% - 50%) of 60KwHr = 24KWhr or 71 miles Leaf: 70% (90% - 20%) of 24KwHr = 16KWhr or 48 miles

OBVIOUSLY a better battery will be HUGELY profitable for anyone who makes it (or steals it). Very likely MASSIVE money is going into battery research and development.

Correction: Bolt: 50%(90%-40%) of 60KwHr = 39KWhr or 100mi effective range.

I.e., how much has the *actual* (original) range been impacted? [If I have a 20 gallon fuel tank on a vehicle, I can almost guarantee that I can get 20 * my_MPG out of that tank. Can you really extract every last watt out of the battery (in the ideal case)?]
