Do you really want a lithium battery in a car? Have you seen what a lithium battery will do when it blows up?

[NickP]

Well, consideration regarding that hasn't crossed my mind Rick but I'm glad you mentioned it. What causes the failure?

[Rick_L]

You're probably aware of some the dangers of lead acid batteries. With a lithium battery the consequences of those hazards increase exponentially.

Basically you don't ever want to short the terminals or overheat the battery, as a powerful explosion could occur.

If you google "lithium batter safety" you'll get pages of pertinent hits.

Lithium batteries have some serious shipping considerations/restrictions.

Lithium batteries have a huge power reserve for their size and weight. Unfortunately the explosion potential is similar.

Lithium batteries are used in the industry I work in (marine oil exploration equipment) because of their light weight/long charge life. There have also been some serious accidents.

Rick I was aware of some of the possible dangers with LION batteries but I didn't know about the material internal to them being highly flammable. Safety certainly is of paramount consideration and I will do dome further investigation prior to making a decision. The really attractive part of them though is their weight to size ratio.
