I just bought a ViewPoint (perfomanceBike) 6V 10W helmet mount light. Of course that was before I read the entire thread. But I still want to mount a rear Xeon(?) strobe.

I have two Lithium Ion Rechargeable Batteries 14.8 Volts ~ 4460mAh Capacity from a laptop. What parts do I need to use them as a power source for the strobe?

I am handy but do not know much about electronics. I can follow directions though
