The M3P DOES NOT have an LFP battery.
I didn't just tell you for funsies.
You said "you don't want to regularly charge over 90% unless absolutely necessary, like for trips. It says it right in the manual as well."
I'm showing you what the manual says.
I also showed you why it's ok to charge to 100% (for non LFP batteries) on the specific conditions I mentioned (not just for trips). I also didn't just tell you for funsies.
This is pretty well discussed on the Tesla forums as well, if you care to look there as well.
