[TenTec] Installing batteries in the Jupiter?

[jkelly at verizon.net]

After looking at the inside of the Jupiter, I was wondering if there is enough room to place 897 (or other) batteries inside the Jupiter to provide portable 12v power.  The manual says 1.5 amp draw on receive - probably not the best radio for this use. Power would need to be dropped to 10 - 20 watts.  Nevertheless, reveiwing the pics on N9VV site shows a lot of room in the radio.  Perhaps the spare jack could connect to the pack and allow charging and a jumper to the 12volt input connector would provide the power when needed?

Any thoughts?
