This looks like it's getting a bit off topic, but the above discussion has made me curious about a couple of things:Your description of rarely if ever doing a range mode charge makes me think that this might be your problem. If it is, you can just do what I did. Be patient, though. While batteries that aren't terribly unbalanced can get to balance in an hour or so, you may take MUCH longer.
1) It's apparent that rarely or never charging in range mode leads to imbalances in the battery pack, but can this in itself cause damage or permanatly decrease range? What if the situation is left uncorrected for months or longer?
2) In order to get the batteries to rebalance, why is driving the car down to a low state of charge before charging in range mode neccessary? Wouldn't charging in range mode from any level of charge accomplish the same thing?
