Cell Temperature
While charging a pack, I noticed that 1 cell was quite a bit warmer than the other 3. The cell on the - side was 100 degrees and the other 3 were right around 80 1300 seconds into the cycle. These are SMC 3300 batts. Charging at 5a with a Duratrax Ice charger. What does this mean? More IR for that cell?

I had a pack do something similar i discharged it on the tray and when i tried to charge it again one cell got hot quick. I checked the solder joints and the bar to see if it was shorting that cell out some how. I never found anything. I tried it a few more times and it would do the same thing and say no batt connected after a min. I assume that cell had gone bad. I shure hated to lose a pack so if anyone knows. I would also like hear some ideas

That means that its coolant is low. Add some water and it should be fine.

I would go on Danny's thread and ask him for advice.

You have to drill a hole in it first.
