It helps to keep the track tension as low as you can before it starts to slip, i noticed in my tiger dramatically increased run time (on an 18ah 12v battery) if the track tension was right. Too high your generating lots of friction. If you are finding you have to run your tracks really tight to get them to grip, I would suggest using a different type of rubber on the drive wheel. I (and others) have found the cheap bungee rubber is very grippy stuff.
