I don't doubt the amazing tech in these small batteries. 7.6Ah is quite enough to start a small car. I just feel safer with a bit more reserve. I also felt that the 30A charge rating of a single pack might be too close for comfort. 60A should be fine with the stock 75A alt.

I think it would be wise to bolt on a charger like the imax or charging harness with diodes and resistors not to kill the lithium battery. Also if it nees a jump start i think that the battery is already dead.
