weird 4200s
 

I was racing on friday and noticed one of my 4200 packs was just very slooooow. i thought nothing of it and diceded to cycle it. i dischaged it down to 5.4v and was about to put it on my equalising tray wen i noteced that 1 cell was realy hot. so i unsoldered the cell and i carnt see anything wrong with it.
my other pack of 4200s i thought id better check aswell so i discarged that down to 5.4v then put it on my tray. i noticed 1 of the lights didnt come on so i checked the voltage and it read 0.00 so i tryed to put some charge into the 1 cell (setting my charger to 1 cell) and it just wouldnt charge.
does anyone now what is wrong with these cells or how i can save them or am i doing something wrong.:confused::confused:
i charge them on a much more cell master at 5A (5.5 if im in a hurry) with 10 peak and 4800 cutoff.
lately though i have been puttinbg them on step charge
step1 5.0A till 800 Mah step 2 till 800 then peak charge at 5.5a with 10 peak
thanks in advance

The one cells dead mate, Bin it and buy a replacement, :D

you will have been racing on 5 cells filltering through the dead one thats why it was slow

Those hot 0.0V cells are dead I'm afraid, I had one go last week. Nothing you can do really other than equalise before charging but those are likely gonners now.

the hot cell had like 1.3 v in it and the dead one was still cool are either of them saveable ??:confused:
