You might want to center the battery more left/right so you don't bias the drive to one side. The side with the battery will have more normal force and therefore more traction.

This might be noticeable in autonomous routines where a driver can't "correct" it by giving one side more power. Give both sides an equal amount of juice and see if it runs in a straight line.
In my experience having an unbalanced robot won't cause it to veer left or right when commanded straight, assuming neither side is traction limited. When trying to turn on point the imbalanced side friction can make rotating clockwise different from counter clockwise, although this difference is much smaller when the robot is moving.
