damage to li from fast charging
Hi All, I thought this may be of interest. https://www.greencarreports.com/news/1127440_fast-charging-method-claims-to-help-electric-car-batteries-last-longer

What is the "supercharge" charging rate? (Where "charging rate" is defined as the initial charging amps per AH of bank)
We see with some Li info that starting at 100% charging rate, it is constant amps until about 65% SOC, then amps taper. Battle Born specifies using a 50% charging rate. We don't have good info on what SOC Bulk would end at with that charging rate, but might be closer to 80% ? We badly need to know that IMO.
So if the car battery loses so much capacity after only a few cycles as in that article, we need to know if the charging rate they are using is way higher than what a typical RVer would use on his Li house batteries.
If anything like the same charging rates, then that is bad news for your poor RVer that went Li :( A weekender RVer with 52 weeks in a year, can soon do 60 cycles like in that article. Yipes.
