you could mount the batterys in some way using like foam under them or some thing like a battery box maybe even a peice of carbon fibre or plastic you couldmount over the chassis. When i say over i am talking about right on top or the part that the cnc milling is milled out.
THIS is what i am talking about and the second pic is a guy that uses this chassis and mounts lipos on the under side for more lower cg.
