&gt; The fire rate in the hobby is very low.<p>As far as I know the percentage of hoverboards that catch fire can also be low. It may be just that RC hobbyists usually don&#x27;t post pictures of their flaming batteries on Facebook with a comment that they are a terrible fire hazard and demand to be taken off the market.<p>For what anecdotal evidence is worth, I know of one house fire and one car fire due to lithium batteries among the members of my local RC club.
