yes the battery is in the back and the arm reaches about 10 ft so far we have never been able to tip it because the way that our drive train is set up

a roller at the front of the triangle
then the 2 drive wheels
then at the back of our arm is another roller

and since it isn;t a square it is much harder to tip because the frame is neither parallel or perpendicular to the drive wheels
