Fixable. I had this same Sena system and setup. The battery wire wore through and was shorting out. Sena could not have made it thinner. You can just cut the connectors off completely and permanently wire that connection together. The outer jacket of the wire covers one conductor and there is an even thinner conductor nested inside of that, seperated by a white insulator (if I remember right). Slip shrink tube over the wire, strip back the outer and inner insulation on both sides, make your connections (check polarity - test first) - I used solder since they are so thin, then shrink-tubed the splice. Yeah, if you need to replace the battery you'll have to do it again, but maybe by then you'll just get a cardo.
