After running the lipos they usually swell up slightly...but they always return to normal after roughly 15 minutes. They also have never gone below safe voltage, in fact, I have never completely run out one of these lipos yet..
Now is it normal for them to swell like this slightly? Its not alot of swelling, just enough that you can notice the cells rounding off at the flat tops just a little bit.

I had a thunder power pack do that once . I came to the cunclusion i was drawing the power out to fast for the battery to handle if that makes since. I have heard the get soft when they get heated up . I dont think that is normal . My 4s FP pack has never done that . What is the c raiting of your zippy pack ?.
