Anyone ever dent their lipo's???

I dented one of mine off a nasty jump the other day, I didnt even realize it until two cycles later. Anyways the zippy-R 4s 4500mah still works good even though its dented. Should I expect any problems from this battery in the future? ( The battery doesnt seem like its puffed at all. )

I had the battery totally wrapped in my battery tray with 1/4" foam rubber, I just ordered some 1/2" foam rubber to give it more protection.

Anyone ever dent their lipo, what was the result???
