I agree with charging each battery with a 12v charger to get the pack balanced.
I have a paktrakr gauge that works the same way to tell you how each battery is doing compared to all of the other batteries, it also works as a volt meter and you can get an amp meter hook up, it's really one of the best meters I've ever seen for the meter, it also gives you a fuel gauge style meter, a warning if you over charge or over discharge any or all of your batteries.
Also after you drive the car a few miles feel each connection on the motor, controller and batteries and see if any are warm.
Also jack up each wheel and spin it around to see how they spin.
I suspect that your batteries are about as small as you can get away with, so as they age they are going to get more and more unhappy with heavy use.
