Lipo runs hot why?

[hoober]

Celcius? If so, it is too hot indeed. It should be able to run much much cooler than a 6S x 3300 in the exact same set-up since it'll make far less power and is more battery capacity. I'm curious as to how long the run was and without that info or the actual battery specifics my first guess is that it is a cheap genric e-bay type pack.
