   Whoops! It works, at least for an 8 amp converter with a .270 amp load.   
      
   The $3 volt meter reads a volt high, but once corrected the voltages add up   
   only losing half a volt somewhere.   
      
   Just add 14.3v to get the voltage and remaining range of the ebike.   
      
   I will now try a 2 amp converter.
