I was doing some looking around and didn't see if this would be kosher or not.
I have a power hungry sensor, and an Xbee connected to an arduino, and I need a nice big battery to power it for a long time. Not sure why, but the 9 volts i'm connecting to it aren't doing the job. I get around 20 minutes or sometimes less out of them before the Xbee starts failing. I was thinking of hooking up one of those big 6 volt battery's to give me a nice long time. Would this work? Should I connect it to the power connector (same as 9 volt) with a regular plug, or should I do something else? Any other inexpensiveish battery solutions for getting a long time with batteries (put 9volts in parallel, ? etc...)?
