eBike battery specifications vary by product and by country.
Certification
A list of certifications that we see from various manufacturers of eBike battery packs:
These certifications cover transport safety (UN38.3), cell-level electrical and mechanical safety (IEC62133-2) and pack-level safety for light electric vehicles (EN50604-1). See Safety Testing for how this kind of abuse and certification testing is structured more generally.
Needs review: this page is currently just a certification list. It would benefit from actual eBike pack examples (voltage class, typical Wh, form factor) and a comparison of regional requirements, similar in depth to the eScooter page.
