Easy AA Battery to PF Functions Motors Adapter?

[__________________________]

I am building an MOC which is having its aesthetics ruined by ugly battery boxes. Has anyone combined a couple AA batteries to make a more compact battery box, then connected that to a PF Functions motor? Also, would this be compatible with Arduino?

Is an AAA battery box still too big, I would have thought that would be smaller than anything you could do with AA. The other solution might be the old style 9v battery box with an adaptor cable, it is just a little smaller than the AAA box.

Or you use one of these, instead.

What about one of these with a custom adapter soldered together?

It has roughly the same capacity as the Lego Lipo battery and the same voltage.

Wow! Thanks, that's what I was thinking of. They're $10 on his Web site. It sounds worth it. Has anybody used these?

Would that provide superior performance?

Thanks for the links! The first one looks pretty tempting. Will have to see if my neighbor has a soldering gun.

Yes, because there would be no current limitations. Unfortunately there would also be no low voltage protections and you would need a Lipo compatible charger.
