2007 TXT controller

[Moose308]

I just recently purchased a 2007 txt ezgo 36v. The main reason was to use it while deer hunting. The problem I'm having is going up a few hills. I have read in a few places that the controller will give me more low end torque. Any thoughts on the problem. I was also told that the batteries were new but i'm not buying it. Either that or the 14" wheels and tires are running down the batteries faster. In any case would a new controller help with the tire size also. Remember I'm a newby to the CART game and I'm ready to figure all this out. Thanks in advance.
