I have a few Integy 1800 mAh 35C LiPos. They have an average of 10 - 15 runs each in a stock Merv. Every one of them has started to bulge. I use a Palm 992 to charge and I charge at 1C or less.

Does this mean it's time to get rid of them? These are the first LiPos I've used so I'm still a noob when it comes to telling what's ok to use and what should be canned.

I've recently bought some SPCs and none of them are bulging so I guess I'm worried about the Integys.
