A fire at a house in Daytona Beach forced two people from their homes Sunday night, and crews believe a lithium-ion battery helped cause the fire.

A homeowner thought he got a great deal on a remote control car at a flea market. Now he thinks the lithium-ion battery may have caused a fire.

Experts, manufacturers, and first responders came to Florida Fire State College to help create rules to prevent and stop lithium-ion battery fires.
