Why the downvotes? Today I tried to return a $200 portable Li-ion power station purchased from Amazon: "Call FedEx to schedule a Ground PRP Hazmat pickup (do NOT take it to a FedEx drop-off location). Hazmat labels and pickup are safety measures for batteries."

Li-Ion batteries are classified as hazmat in some contexts.

TBF LiFePo are used more for EVs, at least the ones that aren't off-brand, and LiFePo isn't nearly as hazardous as generic 'Li-Ion' which usually means LiCoO
