An e-bike battery has caused a fire that left a Sunshine Coast unit uninhabitable and sent one person to hospital.
Queensland Fire Department crews were called to the fire at a two-storey multi-unit complex in Sunhaven Court, Nambour, shortly after 8pm on Sunday.
A spokesperson said six crews responded, with large volumes of thick black smoke coming from the building and an evacuation already in progress when firefighters arrived.
Crews began search and rescue operations before extinguishing the blaze around 8.30pm.
Queensland Ambulance Service paramedics attended at 8.07pm and treated three people.
One patient suffering smoke inhalation was taken to Nambour Hospital in a stable condition.
Two other patients were assessed at the scene but declined further treatment or transport to hospital.
QFD identified a lithium-ion e-bike battery as the cause and confirmed the fire was not suspicious.
No other units in the complex were affected.
