Not to be confused with the Lithium battery chemistry used in phones etc. These don't blow up, they are specially designed for starting, high load, short duration. Plus ... about 60% lighter than lead acid.

As long as it's a Lithium Iron Phosphate (LiFEPO4) you'll be good. I just put one in my street car and holy crap, it's unreal! My old acid battery weighed 20kg, the new LiFEPO4 weighs 4kg -- is over 1000cca and is the size of 1/3 of a shoebox. It has battery management internally so it'll shut down if it goes above 15.5V so they can't blow up and catch fire if the regulator dies etc...
Not cheap a cheap solution, but compared to say an Optima, it was just a few bucks more and saved so much weight up front.
