@ dev null Thanks for that link, I found out that you need a Class D fire extinguisher for Lithium fires. I finally found those little balls Kuji Rolls set up above all his wheels: look up "Auto Fire Off" Fire extinguisher ball (it's only partially class D, so I would go with a class D real fire extinguisher, then have these balls as back-up if you're not home. Whoa, just looked at a class D fire extinguisher and it's over 600 dollars, holey moley! Can someone please find a cost effective solution for us, I will continue to search as well.
