Lithiun Ion Battery Caution

I am sure that any Li battery sold for automotive use in the future will be safe.

Electric cars are using them now, and have been for 10 years. Very few issues.

I had a lead acid battery blow it's top off seconds after starting a commuter van I was refueling. Lucky the hood was down.

Bad thing happen when you store mass amounts of energy in ever smaller packages, not just Li batteries.
