lithium ion car and motorcycle batteries

BTW, here is an interesting blog with some actual experience with the Lithium Iron Phosphate batteries being used for storage. It is interesting for the internals of these batteries used to equalize cell charge and for other 'not so obvious' characteristics, like the fact that they cannot be safely recharged if they ever are overly-discharged... and the role that the internal circuit board plays in preventing this.

And here is seller's informative site link:

Putting in a new but still conventional auto charging system does not address the different charging process that is supposed to be used for these batteries. See the 2nd link. I now have to wonder if the Li motorcycle batteries have a more sophisticated internal circuit board to help manage the charging form a standard car or motorcycle type of system.
