http://avherald.com/h?article=504d93ae&opt=0story from AVH, I pulled the audio.
A United Boeing 737-8 MAX, registration N77259 performing flight UA-2664 from San Diego,CA to Newark,NJ (USA), was climbing out of San Diego's runway 27 when the crew stopped the climb at about 7000 feet due to a passenger's battery pack overheating and igniting. While cabin crew were extinguishing the fire using extinguishers, the flight crew returned the aircraft to San Diego for a safe landing on runway 27 about 10 minutes after departure. 6 people received injuries, 4 of them were taken to a hospital.
San Diego Fire Services reported an external battery pack caught fire, the crew extinguished the fire and placed the item into a special bag.
