those little ground straps are insufficient. on a cold morning your starter uses everything the battery can throw at it, this will be well over 200 amps. at a minimum you want a heavy cable from battery to motor. then you want an #8 min to the frame and the body. additional grounding if you do a big amp or 2.

don't use house wire, it it very stiff and has very few strands compared to welding wire or automotive wire
