Model 3/Y 79 kWh LG (Europe, NOT China): a reliable choice
By shop and owner reports, 79 kWh LG (EU) shows a low rate of serious failures and predictable charge curves. When choosing used, this is one of the most "trouble-free" Long Range 2021+ configurations.
About "EU vs CN": hardware-wise the pack is the same: LG 5L ("M50F", NCM811 cells from the Nanjing plant) went into both EU- and China-built cars. The "EU" vs "CN" difference is the service history of the specific car, not a different battery type.
This article is about the 79 kWh, 2021-2025 generation. From mid/late 2025, Long Range cars from Shanghai/Berlin switched to newer LG "M53" cells (~84-85 kWh), a different pack; see the battery chemistry guide. There's still little field data on M53, so the proven 79 kWh remains the "trouble-free grail" here.
LG pack capacity by generation: M48 ~75 → M50F 79 → M53 84.7 kWh.
The EV Clinic warning (11.2025) and why this article's conclusion doesn't change
EV Clinic claims LG NCM811 packs have a low lifespan: around ~240,000 km versus ~400,000 km for Panasonic, and cell-level repair of these packs is nearly impossible (evclinic.eu). But it is a single, contested source: an analysis by newmobility.news questions its conclusions, and BattCheck SOH statistics show LG's average SOH is actually HIGHER: 91.3% vs 80.7% (sohwhat.com). The TESLA Belarus community's experience is the direct opposite: LG packs in Belarus behave noticeably BETTER than American Panasonic packs. The "grail" stands; before buying, do the standard SOH and imbalance check.

LFP batteries (CATL/BYD) are a good choice for long-term ownership: low degradation with daily 80–100% charging and simple operation. Usually fitted to RWD.
Model 3/Y 54 and 75 kWh (pre-facelift, before 2021): imbalance happens, but less often
The 54/75 kWh packs (pre-facelift) are generally more stable than 82 kWh, but imbalance is possible. What to look at when buying and servicing.

A Model 3/Y pack has 4 modules; one weak module causes imbalance errors. A module swap runs $1,300-2,200 plus shipping in Minsk vs $12,000+ for a new pack.
Model 3/Y 82 kWh Panasonic (US): frequent module imbalance
American 2021–2022 LR cars show frequent imbalances; the root cause is current leaks through the fuse-wire "fingers" of the 21700 cells. Thresholds (up to 8 mV is fine, alert at >150 mV), a breakdown of the BMS_a029/a064/a074/a079 codes from Toolbox, photos of leaking modules and every treatment option, from module repair (tsk.by's recommendation) to a swap to LG 79.
