Ahhh i see. I dont know that im reaching 150f thats about 65C which is the unit we use in australia. my understanding of temperatures is that i would not be able to hold on to a batt at 65C however i will put a heat gun on it next time i run it just to make sure.

i want to change to lipo but im having trouble with all this confusiuon on dischargers, chargers "c" ratings etc.. would anybody be able to help me (by pointing me in the right direction) with a average quality lipo system.. including batteries chargers all i need.

My ESC will handle Lipo i just have to re program it when i get all sorted..

until then i will continue to use theses last three nimh batteries until they die.

thankyou for all your help.
