Watch: E-bike battery explodes into massive fireball inside Oregon home

Home surveillance footage shows the moment an e-bike battery burst into flames and exploded inside a home in Troutdale, Oregon. After investigating a strange smell, a mother and son notice smoke coming from the battery before it erupts into a huge fireball, followed by smaller explosions.

A second angle shows the battery charging moments before the blast, as occupants rush to escape. All six people in the home got out safely, though a cat died in the fire, according to local reports.
