This is easy to fix.
The problem is with junk cells. Simply require UL certification for all ebike battery packs. Limits for over and under-voltage, shorts, and temperature extremes. And apartment complexes will include in their leases that only UL certified ebikes and other mobility devices will be allowed, either indoors or on the property.
Ever considered the enormous amount of energy there is in a 5-gallon container of gasoline? Yet fires are extremely rare because the risk has been engineered out and gasoline storage is not allowed in non-certified containers. Same thing needs to happen with ebikes.
