Model Y standard range battery LFP?

I don’t think anyone can say for sure at this point but all the signs are pointing to it being the same LFP pack in the 3 RWD.

Has anyone actually seen these "internal memos"? Genuine question, I haven't been following this closely, but this sounds like a steaming pile of internet rumor garbage if I'm honest.
Frankly, I find the entire premise of Tesla sending sales and service centers an "internal memo" detailing the charging recommendations for an as-yet unreleased car to be just this side of laughable. This is not a company that has given any outward indication of having their ish together at that level, basically ever.

We will see when the cars get delivered. Tesla employees are often clueless and could be misinterpreting something or the person that asked their Tesla store is misinterpreting something. It’s all a game of telephone since I don’t think anyone had posted a photo of the actual memo.
Before the new Model 3 LR was released people were saying their Tesla advisors claimed they would be LFP and all the Tesla bloggers and YouTubers ran with that. It was not true.

Oh, I was not aware of this. Haven’t been keeping up on the differences between the 3 and Y. So Reno is just making Y and PowerWall cells?

The original SR 3 was 220 miles (software limited) if I remember correctly. The SR+ was 240 then 250. The original SR Y was based on the SR+ 3. The new SR Y would likely be based on the current SR 3 which uses LFP. There was never a 180 miles rated on release to my recollection.
You don’t have to look at additional vehicle info, you just look at the charging screen and see if it has marks for daily charging vs trips. If it has those and recommends 80% for daily charging it isn’t LFP.
I have the original SR 3, which was 220 miles (software limited). It's now showing 180 max. I wonder if SR Y will have that problem too, with the additional 40 miles or will LFP/better battery chemistry help with range/charging.

That “180” number is just a matter of the battery management system and how it calculates potential range. I wouldn’t say your car is rated at 180 miles right now. There is a very thorough thread in the M3 forum that talks about how to calibrate the BMS and “regain” more range. You should be in the 10-15% degradation range, not the almost 20 you are experiencing.I have the original SR 3, which was 220 miles (software limited). It's now showing 180 max.

Regarding LFP vs NCA degradation, there are many other threads and articles on that on here and elsewhere on the internet so no need to get into it. All rechargeable batteries have degradation over time and recharge cycles. And all batteries are subject to how you recharge them and how the BMS is able to calculate that based on usage and charging. If your battery only operates in a small range (60-80%, always plugged in as Tesla suggests) it will be more likely to be off until it has multiple times to take readings at different SoC.

Reps don’t always know everything. Could be taking SR M3 info and applying to SR MY. Wouldn’t be the first time.
Hasn't anyone test driven one recently?
I test drove a Model Y RWD a few days ago. The Additional Vehicle info did not say High Voltage battery type: Lithium Iron Phosphate. Also, the charging screen recommended charging to 80%.. BUT I asked the manager and the three reps there and they all said it was LFP. And that was a software glitch. Not sure I believe them!
