I charge my Tesla to 267 miles each day. Yes 300 miles is enough. CATL new LFP battery for main stream EV s supports fast charging of 250 mile in 10 minutes. Used in Tesla and GM entry level EV 2024 on.

My point about 900 miles is really that it is possible by 2030 for the same price as. 300 mile range battery today. So the market acceptance should jump.

By the CATL early LFP battery has an expected life of 1,200,000 miles. CATL offer batteries for buses with 900,000 mile or 15 year warranty.

Could EV vendors offer an expected warranty to say 500,000 miles and 15 years for say $200 (and make money on it) ? Yes.

Price, range and battery life could be non issues by 2030. Consumer knowledge will grow and gravitate to 300 mile range.
