I donno bout the 3AAA one. I' don't have one. I'm using the 2AA one and it's completed. 2 14500's in parallel drive the 7135 driver. it doesn't get below 3v very easily.

not when they are in parallel. they are 3.6v. just ups the mah. I can't take pics yet cause it's currently sitting in the manufacturing companies hands as a similair design.

parallel means hooking two batteries to the same thing in parallel not series. Research a series circuit and a parallel circuit. Both positives go to the same source instead of to the other negative on the other battery. I cannot explain it here if you don't understand your going to have to see a physical representation.

Parallel:
|---(+)Battery(-)---|
-------| |-------
|---(+)Battery(-)---|
Series:
------(+)Battery(-)----(+)Battery(-)-------
hope that helps

that does help. I tried doing that but just couldnt' think of a way to show it. by running in parallel you in crease the battery's mah instead of the voltage. by running in series you increase voltage but not mah.

I did a simple dummy board with metal arms (springs) on the sides to ground the top section to the barrel and a ribbon for a dvd-rw. The dummy board goes in between teh two batteries preventing them from shorting out to one another. The ribbon goes from the positive on the bottom battery to the bottom of the driver board. So both batteries make connection to the top by means of direct connection for the top on and the ribbon for the bottom one. Here is an illustration of exactly what I did to drive this in parallel.
