Xbee/Propeller battery reccomendations

w4fej

I am building a remote control unit using the 60mw Xbee pro. The unit will be housed in a handheld enclosure about the size of a large digital VOM. There is a small slanted front panel area for the Parallax 2 x 16 serial display, a two axis joystick also Parallax using MCP 3202 A/D to read the Joystick. The Propeller is a "Spin Studio" board with both 5VDC and 3.3 VDC available.

I have already resigned myself to having the battery external to the enclosure either mounted to the bottom of the unit or maybe even a tether to a belt mount etc.

I have seen a lot of print regarding Li-Po batteries but I have no experience at all with them.

Take me to school on how to power this handheld controller with the "high power" Xbee pro...

Thanks for reading...

I made an XBee-based remote control a couple of years ago.

I got the XBee's 3V from the system 5V by using 3 silicon diodes in series. I also put an LED on that output for a minimum draw and as a 3V good indicator.
I didn't use any fancy batteries, just a 9V alkaline as source/V_in for a 7805SR (which has good/great efficiency even at low current.) Batteries, unlike many other things these days, have become less expensive [or is it just me?]
