Brad,

I can't do a full discharge test yet as I don't yet have a LiPoly protection circuit built and don't like objects that explode. But I'm using both the 100mAh and 860mAh batteries from Sparkfun.

I wouldn't mess with trying to tie the charging into the Gumstix/Audiostix USB, to be honest. At the very least, you'd have to cut the traces to the onboard regulator. And you'd have no protection/switching circuitry.

Seems to me like any gumstix that can plug into a usb should integrate the max1555 on it's board. Seems like a reasonable RFE for the next gen expansion boards.

I would actualy go so far as to make a Breakout GS board with an integrated lipoly on it (with the max1555 to charge it).

but that's a bit off the subject.

Since I'm using a Robostix I have to have more than 6v.
I plan to use these batteries from tenergy: http://www.all-battery.com/index.asp?PageAction=VIEWPROD&ProdID=988
I'm using two of these one to power servos/motors, and the other to power the gumstix/robostix logic.

I'll post some stuff on the wiki when I get everything working.
