According to Raymarine documentation, the E7 operating voltage range is 10.2 - 15.6 volts.

    My new E7 Raymarine chartplotter reboots when I start the engine (a Perkins 
diesel).  Cat's Paw's batteries are quite new, fully charged, and hold their 
charge well.  But obviously the voltage drops when cranking the engine.  None 
of my other electronics is affected this way, including an old CP 150 Standard 
Horizon and a 2007 CP300 chartplotter.  Apparently the E7 demands a higher 
voltage to keep from crashing.
     Best way to deal with this?  Others must have a similar problem.  I could 
put a small rechargable battery just before the panel switch to the E7 with a 
diode to the main battery, so it is kept charged but maintains enough voltage 
to the E7 when the main voltage drops.  But I bet there is a better solution. 
Suggestions welcome!
