I know, I think 14 cells is a good match for 9920 and 7XL. I think though that 4s lipo is more like 16 cells. I know they are 14.8v, but that is almost at no charge. Fully charged pack seems to be more like 16.8v? And it puts out higher constant voltage than nimh cells, nimhs start to drop off very quickly and loose a lot of punch into a run, where lipos run strong till they dump.
More avaliable current over longer duration equals more heat for longer time.

I think I've weakend my 9920 anyway by thermalling it really hard when I first got it trying to run a 6XL, I shorted it once too and metled the shrink off it! I didn't even think it would work anymore, so much smoke came out. Maybe that's why I have thermalling problems?
