Good day all,
Here is the scenario. I have a 12v device and a 6 volt device I need to power.
Can this be safely/efficiently accomplished by using 2x4 AA battery holders and run them in series, making a connection in between the two packs to get 6 volts from the first pack to power the 6v device, while powering the 12v device as well by running it in series with both battery packs? This will drain the current on the first pack faster than on the second pack correct? Is this ok?
Edit for clarification:
My 6v device will draw 100ma continuously and be in use for only a few minutes at a time, 5v is its minimum operating voltage. My 12v device will draw 330ma transiently, none when not in use, 12v is its minimum operating voltage.
I plan to use L91 lithium AA for maximum mah.
