Back from the 150 mile trip, and after over 9 hours, the weaker cells seem to have gradually risen in voltage to nearly the same as the stronger cells. The subpack sitting in my tester, where it could cool easily was about 8 degrees above ambient.
I suspect that a whole pack full of subpacks would get much hotter even at 350ma, especially in the center, if the fan was not running.
Note the rather big cell voltage difference when the quick charge started, and also when it ended. The slow constant charge may be required to fully rebaalance the cells?
I will let it soak till I go to bed, and see where things are tomorrow AM. Then I will do a discharge to see if the unbalanced condition returns. We may finally get to see the rebalancing process at work?
Should be very informative.
