Sounded to me like he pulled current from them all based on their soc but I am not sure how one could pull that trick off.

(v) I don't think they did the same thing. I think Better Place did what Tesla is doing - allowing the entire battery to be swapped. Shrinkle divided his battery into 12 smaller batteries and is, if I understand correctly, only drawing energy from one of the batteries at a time. Thus you only need to swap the depleted ones, not the entire set of 12.
