IBC 3800 cell pack problems

[Major Azzwoopin]

Any one had any issues with these cells?? I was running my stock emaxx with the 3800 7 cell packs Mike made up for me last fall. I had run the 3 charge and discharge program on my schulze through them a couple of weeks ago to freshen them up. Well one of the cells in one pack popped on the positive end and started spitting and leaking inside the shrink I put on. This happened on discharge. The other pair of 7 cell packs discharged fine but another single cell did the same thing in another pack as the charging cycle finished. Any ideas?

Maybe it was from sitting. Did you any charge in the packs when you stored them?

I have heard of the IB's having problems with shorts but not many in the 3800's but it has happened

Yes there was a charge in them. Whatever I had in them from when I last charged them, after my last use.

Maybe discharginig down too far?

on the first set that popped before I charged yes possibly (I didn't know you could discharge too far???), I was running them when they were low trying to completely discharge them. but the second set didn't pop a cell until after the charge cycle. and it was kind of weird I was feeling the cells and measuring temps with a temp gun, and they were cool right after the charge but the temps kept climbing until they popped, the popped cell was causing the cells next to them to increse temps as well so I unsoldered the popped cells from the pack. After things stabilized I put new IB3800 cells in the packs. It looks like the 3 of the packs are ok, but I have one pack that is low on voltage so I think I must have a bad cell in that pack still....I hit the pack with the charger again to see if I just forgot to start the charge cycle. The other odd thing is that the cells that popped still have good voltage in them now, at least 1.29v.
