We used a dual servo mount for our battery holder, plus 2 zip ties and it was very sturdy.

That reminds me of another issue: We originally had our battery resting on two bolts. Probably a bad idea, because it shorted and caused the battery to heat up melt the blue plastic insulation.

We used the pivot bearings in our robot at one time, are you using them as suggested in the instruction manual?
