I have one experience with a Ballistic. I had a customer install a 16 cell in his Harley (trouble bike, S&S, big inches, and no compression releases) and after a month the battery melted itself on startup. Called Chip at Ballistic to find out what happened and he blew me off. So I never ordered any to sell and prefer to wait on the fence until the technology is a little older.
I will say it's good that the battery did not catch fire like other Lithium technology batteries such as Grrreen or whatever they are.
For now I will stick to selling Deka and Odyssey as my top end motorcycle products.
