So if you just plug the charger in to the wall, once its fully charged, does the charger shut off, or does the lithium cell pack passive circuit just stop the charger from overcharging?

Reason i'm asking specifics, is I wonder if you need to run the charger on a timer, so that it will shut off after 5 hours, to let the passive circuit run for 30 minutes and balance the cells. I read on that site batteryspace.com that after charging up the lithium pack, you need to allow that 30 min to balance...

For now i'm just playing around with my regular old lead/acid starting battery, but want to make sure all my research is right before I go dumping a bunch of cash on this. My main concerns are how long can i drive, which correlates with the available AH, max discharge allowed, and amount amps my car pulls with load and without.
