What causes hoverboard a to blow up?

Hoverboards can catch fire or explode primarily due to faulty lithium-ion batteries, which may overheat due to manufacturing defects, poor quality control, or damage. Overcharging, improper charging practices, or using incompatible chargers can also lead to battery failures. Additionally, inadequate thermal management and design flaws in the hoverboard itself can contribute to overheating. Ensuring proper safety certifications and using high-quality components are essential to mitigate these risks.
