Well I just noticed something.
After taking the truck out for a run (ESC has a 4S or 12V cutoff btw) I temped everything and the batts were 120, ESC 140, motor 140. Not bad? I didn't think so.
I stopped running after about 10 minutes, way before the voltage cutoff would have come on. Usually get about 20 minutes of runtime (approx.)
And then the next day I was going to charge up the batteries when suddenly I noticed the packs looked a little "bigger" than usual. I picked one up and set it on the table and it sounded funny, like it was hallow. I pressed down on the center and it felt crunchy. Great, like I need this to deal with also

No running until late august now until i get new lipos now i guess.
(They are Maxamps packs BTW....)
Does this stuff happen to any of you guys? Never had a lipo fail like this before, expecially since I didn't do anything out of the ordinary. I didn't treat these any differently than i've ever treated any other lipos and I have never had any problems up until now...
