Model 3/Y 82 kWh Panasonic (US): frequent module imbalance
Symptoms
- Rapid growth of imbalance between groups, prolonged balancing, reduced available power/charge.
Solutions
- Replace the defective module or the entire pack.
- Upgrade/replace with LG 79 kWh (EU/China) — a more stable option per shop practice.
Belarus budget
≈ $1 500–7 000 depending on the scope of work / donor availability.

Community experience TESLA Belarus
Analysis of 400 000 messages from the TESLA owner's group BELARUS chat — one of the most painful topics.
Step-by-step solution from chat (balancing without replacing modules):
- Discharge the car below 20%.
- Find a charger with 5+ kW that doesn't drop the session on pause (NB, EVICA in Minsk).
- Start Battery Test via Service Mode.
- Wait 12-18 hours — the BMS balances the cells.
- Repeat once every six months as prevention.
- Do NOT use CCS for the test — only slow charging (Type 2 / Wall Charger).
