Low-voltage battery warning after software update

Don't clear the alert just to make the screen pretty. Leave the alerts on the 2023 Rivian R1T so service can see what you saw. That's where I'd start. This is from a 2023 Rivian R1T in Nationwide with 151,000 miles. I'd want a dollar figure or a measured spec, not 'should be fine.' Doing the boring step first on purpose.

Charge curves lie if you don't match starting SOC and temp. Match starting SOC and battery temp if you're comparing 2023 Rivian R1T charge sessions. I'd do that before spending real money. Post the numbers (or the code) and people can get more specific. If the story changes I'll post the new data.
