The stock ones are made in Japan, if memory serves me they have a Denso logo on them. I wouldn't doubt the actual integrated circuit is outsourced from China however, why would they bother making one in-house? I don't think it will be a problem and you can move it to a place with better cooling so it will survive longer. The stock mounting place is the reason why it fails. I actually built my own battery box for my 848, which allowed me to move it further up the fairing, worked great! Just takes a bit of ingenuity!
