[TenTec] Argosy on Battery

[John]

I am planning on taking my Argosy on the road this summer and will need 
to make a new connection to utilize  a 7 Ah battery (removed fire 
detector stock.)  Do I need to put a switch and current limiting in line 
in this application or can I just utilize a 4 pin mate-N-Lock connector 
using just the power connections.  What have others done in regards to 
portable power for the Argosy?  If I stay at 5 watts is 7 amp hours 
enough capacity?

As an aside, I am also putting together a portable vertical that will 
cover 60M to 10M with enough adjustment range that a tuner will not be 
required (AD5X design.)  I am looking forward to seeing what I can do at 
QRP power at lunch stops, rest stops or even radio stops.
