Tesla Model 3/Y LFP 60–64 kWh (CATL/BYD): durably reliable, but RWD only

LFP characteristics

• Better tolerates frequent charging to 100% (Tesla recommends periodic 100% to calibrate SoC).
• Calmer degradation at high SoC compared to NCA/NCM.
• Limitation: typically fitted to RWD only.

Capacity note (CATL generations)

The numbers in the title are a timeline, not different versions that coexist (per the European tff-forum Akkuwiki):

• 2020 (CN) / 2021 (EU): CATL “LFP55”, ~55 kWh (early batches software-locked to ~54);
• 2021-2024: CATL “LFP60” (BTF1), ~60 kWh net / ~62 kWh unlocked;
• 2025-2026: CATL “LFPx / LMFP” (6M / BTF2), 64.5 kWh.

So “62” and “64” are different packs (LFP60 vs the newer LFPx), not the same pack counted two ways.

Separately, BYD Blade ~60 kWh on some Model Y SR 2023-2024 (Berlin/Shanghai).

For comparison with NCA and NMC packs, see the capacity and cell count of every Tesla pack.

Service life: the first failures at high mileage

The "LFP is durably reliable" claim holds for ordinary use, but it has a boundary. Among Belarusian taxi drivers covering something like 100,000 km a year, two LFP packs died within a single week (2026), at 120,000 and 164,000 km (#461450, #461452). These are the first LFP failures known in the community: not a mass pattern, but not "never" either.

The symptom is specific: the high-voltage system shuts down during fast charging, and the screen demands that you park immediately and leave the car (#461451). From the outside it looks like a dead 12/16V battery, so that is what gets blamed first and time is lost. If you catch this on an LFP past 100,000 km, run the diagnostics on the HV side and the BMS codes; see the BMS code decoder. A pack replacement, per chat estimates, runs around $12,000 (#461452).

What you do not need to fear

Two YouTube scare stories that LFP owners disprove in practice (#508633):

• "Calibration at a 100% charge takes hours": it does not. 99% to 100% takes 5–10 minutes, and you can skip the procedure entirely if you like; once every week or two is enough (#508630, #508632, #508638).
• "LFP self-discharges while parked": a parked, sleeping Tesla has no self-discharge on any chemistry, and LFP is no exception (#508618).

One limitation is real and purely wintry: on a cold LFP, regen and acceleration power are cut, and the car barely slows when you lift off the pedal until the pack has warmed up (#508620). How regen behaves on ice, and how to avoid a skid, is covered in regenerative braking on icy roads. Range drops in the cold too; one LFP owner notices it already on +10 °C (50 °F) mornings (#507670).

How to tell you have LFP

• In the car menu: Controls → Software → Additional Vehicle Information. On an LFP car the high-voltage battery type reads Lithium Iron Phosphate (#45671, Recurrent).
• On the charging screen: tap Set Limit. An LFP car shows 50% and 100% marks on the battery image, NCA/NMC cars show Daily and Trip (#45670, Recurrent).
• By VIN: only by plant and model year, decoded in the battery type guide. For US-built cars the VIN is not conclusive, so the two checks above are more reliable.
