I agree that OE plays a part in every accident. I still think that being able to hook up one battery to the charge leads and another to the balance leads is a bad design. This is only true of chargers which have the balancer built-in. I always use a stand-alone balancer, which makes it extremely apparent whether the battery I'm charging is also the one I'm balancing/referencing. And yes, the charger should use the main leads as a cut-off voltage reference. It's obvious that in this case it didn't. The balance tap reference is more accurate, but the charger should still recognize that the battery is being overcharged from the voltage at the main leads! UNLESS the cell count is wrong.
