Hi Vic:

Modern portable equipment that uses multiple Li-Ion batteries have a protection 
circuit that monitors both charge and discharge of each cell in the battery. 
This requires two heavy wires for the input/output of the battery and in 
addition a small voltage sense wire for each cell.  Not doing this can lead to 
nasty flames.

Notice that the battery is made up of three cells and only has a two pin 
connector.  The battery is described as "Solid".  You need to be sure you can 
get to the needed inter cell connections so that the protection circuit can be 
installed.

If you choose to work with the battery without a protection circuit you might 
consider getting one of the fire proof bags the RC airplane guys use with their 
unprotected batteries.  That way you don't loose your car when the battery goes 
pffft.
