Two firefighters sustained minor injuries Feb. 8 while battling flames in a two-story house on 48th Street between Sixth and Seventh avenues.
The two-alarm blaze started in the basement at around 3:30 a.m. and spread to the first floor.
Twenty-five units and 120 of New York’s Bravest put out the fire by 4:50 a.m.
The FDNY said a replacement lithium-ion battery for an e-bike sparked the incident.
“[The owner] did not know if that battery was certified or where it was manufactured,” Chief Fire Marshall Daniel Flynn told reporters.
