The fire, which broke out on Sunday in Sydney and fire investigators believe a faulty lithium-ion battery on the bike exploded, causing the fire, which has badly damaged the home and destroyed a car in the garage.

Firefighters removed several other lithium-ion batteries from the scene, amid concerns they had been compromised by fire and were at risk of igniting or exploding.

The e-bike battery was immersed in water by firefighters to prevent re-ignition. They remained at the scene overnight to monitor the situation.

FRNSW issued a statement warning that faulty or overcharged lithium-ion batteries pose a serious safety risk. They can explode, causing intense fires that are extremely difficult to extinguish and are at risk of reigniting.
