I appreciate all the responses. Sounds like the Sena extended case may be the way to go. Maybe I'll wait a bit to see if they decide to offer an extended version of the Aximsite case.
Kelly - looks like you've not only traveled to Afganistan, but also several months into the future if you got your Axim in December 06
But I digress ... are you saying that you dumped your extended battery for the power pack? I am assuming that you got rid of the extended and now use the power back in conjunction with the standard battery - is that right?
