“I have only used this one once- it worked well. I have been flying this same type battery about a year and very happy with it. Not a bit of swelling.”
“I heard a lot of good things about these Admiral packs from MotionRC. Purchased these as they are slimmer than the ones I've been using (which is nice because I can fit them in tighter fuselages). However, I feel they don't have the same ooomph as my other packs from a different brand. I've only had a few flights on them so we'll see how long they last and if they would get stronger once properly broken in, They were balance charged and mildly discharged on first couple of flights to ensure proper break-in. Time will tell.”
