What some people are missing is that this thread IS NOT about Li-ion batteries, per se.
These have proven themselves to be very reasonably safe --- if manufactured and used properly.
It's about trying to reduce hazards caused by poor quality batteries, and/or improperly matched chargers.
Just about every electrical device in the USA, from building wiring and panels, down to handheld electronics conforms to UL, CE, ANSI, or other standards to ensure fire and shock safety.
It borders on the incomprensible that the sizable batteries in E-bikes have fallen through the cracks, and been left there so long.
The point is that it's very possible to build and charge Li-ion batteries safely, but we have not chosen (so far) to deal with those suppliers who simply don't bother having any quality standards.
IMO, while state and local regulations are a start, we need to adopt national standards and block shoddy E-bike electricals at the POE, the same way we do other hazardous items.
