Battery Health - LFP "Usable (new)" calculation not realistic

[denzel1994]

Is there an existing issue for this?

What happened?

The new Battery Health - LFP dashboard shows me 83.7 kWh for a new battery. I have a late 2021 SR+ Model 3 with the 60/62 kWh LFP battery.

Expected Behavior

The normal Battery Health Dashboard shows correct values:

I have a 2022 SR+ Model 3 which was the first official 2022 cars delivered in North-America (Canada) with LFP batteries as I received it in January (In the USA few SR+ LFP cars have been shipped in Autumn 2021 as part of a testing effort if I recall it). I dont have the problem reported here. Would it be possible that the late 2021 cars had a different LFP batterie? (I am not searching for an answer, just mentioning it in case it could help resolve the situation, although we dont know from which part of the world the owner is reporting this situation).

The only difference that I am observing is about the expected results that show an "Usable (new)" value of 60.8, while I receive a 60.4 value.

Reporting from Germany. :)

I am just wondering because in (#3311) it states:
"Battery Health - LFP: The current SOC bar has a red zone only on the lower end."

Meaning the Battery Capacity calculation should not have changed compared to the "Non LFP - Battery Health".
As mentioned the "Non LFP" Battery Health Dashboard shows realistic values that can be backed up by Scan My Tesla BMS Data.

I had a similar issue with in original Custom Dashboard:

It got resolved in his issue:

Works for me with 03/2022 SR, too. 61.0 kWh usable (new).
