Is there a simple way to power both 6 and 12 volt devices from a 12 volt battery? Answered
I wired up my bicycle with a 12 volt battery. The problem is, I have a Cree MC-E led which requires between 5 and 10 volts with a buckpuck. One person suggested resistors to drop twelve volts to nine but that would waste too much electricity. Is there a simple way to cut the voltage in half to six volts which would not loose power in the conversion process. Cutting the power to 6 volts would be best because there are devices aside from the light requiring 6 volts which I want to install.
