If avoidable, you wouldn't want any pvc 'grip' at all. Excessive drag forces could attribute to some of the wheel slip. Perhaps you could figure out a way to make the pvc guides into rollers so there's less resistance.
The placement tweaking of the battery is a manipulation of the c.g. in order to acquire more normal force to the pole for your traction wheel. It works in the same manner that the mechanism at 1:27 in
this video works for creating normal force to the pole. The c.g. relative to the pole was
out from and
below the driving wheel, while the idler wheel was
above it. If you've already put it where you can based upon the sizing constraints, then that's about all you can do for that.
