A123 charging problem

[JThiessen]

It seems that my battery saga will never end. I HAD thought that I had found the solution with the new A123 packs and new Hyperion DUO. I ran them twice, and they have more punch than I can drive right now. My packs are A123 brand, 6.6V 4600 (2s2p). I run two of them in my Revo with a HV-4.5.

I was initially concerned that I couldnt use the A123 balancer since the plug didnt match up to my chargers balance ports, but an actual customer service email from A123 they said I didnt need to worry about it (maybe it helps that I sent it from work - they'd love to have our airplanes running A123's!).

So yesterday, we ran the trucks hard enough that we both came home with broken parts! Tonight I put the A123's on the charger, but with each set of batteries, the charger only detects 1 cell (3.3V) on one battery. Did I most likely damage a cell on each one?
