hey guys, I need a little help.. anyone can tell me exact weight of an EP4200 cell? I don't have weights around and it's pretty urgent.. Thanks in advance!

Its aprx 450grams w/deans connector installed.

Anyway, I did check my IB packs (5X) a few mins ago because my car lost its punch last weekend and found out that 3 out of 5 packs that I have has a dead cell on it

my IB packs are not even two months old

I do use a discharging tray and discharging it at 1.2 volts/cell and Im only using a 27T BL motor and charging it at 5.5amps.

I don't remember having any problems like these when we had Sanyo 2000 mAh cells

Yep I agree

No you did nothing wrong if it was like that when new. With IB pushing the cells to their maximum performance level that most racers want it's a side effect that IB has yet to figure out how to fix 100% but they have gotten a lot better. There's not much a matcher or consumer can do to avoid this other than follow the reconmended storage methods and if one goes dead contact the matcher for replacements.

I bought some SMC a few years back, one of the cells was pooo, contacted kinetix where i got them, he in then turned me to Danny, Danny said he would replace the cell, then a new pack showed up with the current highest numbers!

cant beat that~
