I have a lithium battery pack made up for my 3500. It was made up by Woody, it has come apart and is only showing 1 volt on multimeter. Yet showing fully charged on charger. The hot melt glue inside has let go.i have previously superglued it but now it has let go again. How safe is this could it burst into flames. These batteries are Canon camera batteries modified and fitted with minelab leads. Got me wondering?
