E-bike batteries were still catching fire Friday at HQ Ebike Repair Shop in Manhattan’s Chinatown, days after lithium-ion batteries in the business exploded into a fast-moving fire that killed four people.

Sixty firefighters and EMS personnel responded to a new blaze in the building at 80 Madison St. around 6 p.m., the Fire Department said.

A pile of batteries at the site “just ignited,” said witness Belal Alayah, 25, who works in a deli across the street and who said he called 911 to report the deadly fire on Tuesday.

“I smelled the fire at first, and then I stepped out side, and it was burning again,” he said. “I had to kick people out of the store, because the fumes were so toxic”

The batteries also caught fire on Thursday night, Alayah said.
