Seems like the insulation needs to be cut back some more so the wire fits deeper into the connector. Could very well explain why the MMM's keep failing on big jumps. I had this happen before with nimh batteries where a battery bar came loose but would sometimes make contact. I beat myself to death trying to fine a problem before I cam across the broken bar. The batteries were held together so well by epoxy that it was only noticeable upon close inspection.
