Best done with the pack under load.  A "dummy load" is darned useful for 
this, but if you don't have one, at least run the motor in neutral, or 
jack 
up the wheels.  The one with the lowest voltage is the problem child.

You can also measure voltage of each battery shortly after starting the 
charger (measure with the charger running).  The one with the >highest< 
voltage is apt to be the stinker.

     The difference between the US and the EU is that they're a 
     post-industrial democratic society, and we're a post-democratic
     industrial society.  Think about it:  Where else in the first 
     world is the party currently in power also allowed to manage 
     elections? What other nation manufactures more weapons and war?
