Your custom high-density Lithium-Ion (Li-ion) battery pack harbors a critical danger: Thermal Runaway, a catastrophic chain reaction leading to fire and explosion.

This professional-grade 7-Point Safety Audit is specifically designed for serious DIY Powerwall and EV builders. It details the precise failure points—from cell internal resistance (IR) imbalances to inadequate pressure venting—that are unique to non-commercial packs. This is not a theoretical guide; it is the definitive, mandatory checklist for protecting your property and life. Do not commission your battery until you pass this audit.
