EV Batteries Are Dangerous to Repair. Here’s Why Mechanics Are Doing So Anyway

Absolutely, but 400V isn't as dangerous as 1,000V. IEC standards have already established all of this, above 1,000V is HV, below 50V is ELV and generally safe. Automotives have come in and labelled anything above like 24V as "HV", which is just silly.
