Thanks Socket. My problem is I'm using a Turnigy Reaktor 30amp 1000W charger. It is a rebranded version of the older, Icharger 306B. Don't know if the algorithms in the older Icharger are applicable. I'm wondering if I should buy this separate unit with a fan, adjustable discharge voltage/amperage, or purchase a separate discharger resistor (or do anything but just discharge to rebalance cells).
