I am trying to hack an 18 volt drill battery. I'd like 2 feeds coming off of it, 1) 12 volt 1.8 amp for led lights 2) 5v 2 amp. USB for phone charging They may or may not be running at the same time. I am trying to do the most efficient use of power conversion. Do I use a voltage divider circuit with resistors or 2 buck converters? Is there another way, seems like it should be simple. I am a pretty good "maker" but not great at electronics theory. Any help would be appreciated. |

I'ld use the two buck converters. They will certainly be more efficient than resister voltage dividers---and the resister approach will probably give more voltage droop under load. |
