I am hoping it is just the battery... but could the battery have damaged anything else?
Swelling like that can occur to some degree as the lipos age, but over-discharge can do it prematurely, as can over-charging. But the battery's small protection circuit board should prevent both of those IF it functions properly. I doubt if they are highly accurate or reliable, though. The #11 also has a chage IC on the main circuit board as well to mange the charge.
I have quite a few flight power lipos that have puffed up just from aging.
