Hello, this kind of temp is the CD is normal, I hit the same in my truggy with a 1520/1Y. Are your wheels really balanced ? I had temp issue with non balanced wheels, which is always the case when you use monster truck wheels... Try maybe to do some air flow in the body, that helps a lot...
The hot batteries means that you are pumping of lot of amps, can you reming us your mph gearing setup, the weight of the truck and the type of batteries ? Maybe something is wrong in the transmission, and that would explain this temps.
