A good lithium ion battery supposedly has a built-in battery management system that will prevent the conditions that cause the battery to catch on fire. Of course that's no guarantee that there will never be a problem. But that's why it's a good idea for us to keep track of what brand of batteries have the fire. I have been using anti-gravity batteries with no problem and they claim to have a superior battery management system, such that you can use the cars alternator to charge it for street driving. I have done just that on drag week.
