just a question,

I have 4 x 4200's and a much more charger, both bought at the same time and not once have I ever been able to charge these packs at the recomended 03 - 05 mv cut off setting as stated in the manual. The only way I can get a full charge is to use the CTX charge mode set to a linear charge curve with a long lock out (20min) and a minimum 18mv cut off setting. I have temp set to 50c and only on a hot day charging in the back of my car has it switched off because of temp. This way i'm averaging around 4400 - 4600mah per charge which seems normal.
Could it be that my cells are faulty (matched fantom packs) or that the charger is too sensitive ? Because using the normal charge mode (03 - 05mv cut off) all the packs false peak all the way through the charge curve.

Cheers
george.
