6 of them are really usable. That leaves 10 that ain't so good.
I sorted out the 6 best to put in the Metro.
It looks like possibly the best way to go is to keep the car at 72V right now. I am not sure how much better range I would get by adding 6 more batteries of poorer quality, especially since I don't have individual battery monitoring.

Well you know what I'm going to say, right?
Get yourself a monitoring system. Quick! Before you torture any of your good batteries. You might be torturing one of them right now and not even know it!
(Trying to put the fear of battricide in ya. Is it working?)
You don't even need the fancy 10 LED array per battery like the ForkenSwift has. You can do a much more simple 1, 2 or 3 LED setup that would be cheaper to assemble. Of course, the more LEDs the better resolution, and the more you can see what your right foot is doing to your poor batteries.
Heck, you could even get 6 dirt cheap voltmeters or gauges. But get something! And then you can be assured of keeping things above 1.75v per cell (10.5 per 12v batt)... battricide territory.
