   Thanks for the explanations.   
      
   Yes, there is a charging circuit between the solar panel and the battery   
    as well as a protection ciircuit embedded in the battery pack. (ordered   
   from some custom place in california).   
      
   In terms of connectors, I have sellted on RCA jacks with well soldered   
   heavy duty wiring with the insudes filled with silocone. I have found   
   those to resist vibration very well. (and polarity is easy to manage   
   correctly).   
      
   I need about 7 switches to control the systemto give me the flxibility I   
   need to isolate parts and choose between running components directly   
   from  the solar power or from the battery (wit power also coming from   
   solar charger).   
      
   But for the GPS, I want automatic switchover. On the other hand, having   
   automatic switchover for everything may also be desirable (am in the   
   process of designing the switches and wiring/connection between components).   
      
   My previous system was in one unit with a walkkan attached to it via   
   velco and connections via ribbon cable that came out the back of the   
   walkman.  It ised NiMh  batteries with no charge controller. So it was   
   easiler because with solar power directly into batteries and devices   
   drawing form that, it was automatic switch from solar to batteries.   
      
      
   So, I got some model numbers, ANd I have seen documents that show how to   
   get device number/name from the colour bars.   
      
   But if I need a diode capable of 50v and 2amps, how do I convert this to   
   a part number ? Isi is a case of having to browse through spec sheets   
   until you find somethint that fits the bill and then get that part number ?   
      
   (or asking here and get suggested part numebgrs as Paul and others have   
   done).
