Hi, can Teslafi tell me what kind of battery I have ?

The Tesla staff swore blind that my Model 3 Long Range Made in China has LFP batteries.  I don’t believe them, and if I regularly charge to 100% as they advised it could ruin my battery.  But is there a definitive way to check.  The manual says that the way to check is the charge screen, if it has percentages then it’s a LFP but not if it has Daily &Trip.  Mine has Daily & Trip.  Also the car is not any heavier and and vin decoder says it isn’t LFP.

Yet, the staff here in France all insist that it’s LFP but won’t provide any proof.

So can this app tell me?

Thanks
