Re: voltage

I leave mine set at 10.0 volts, however while I am fishing my battery volts has never dropped below 12.4. Sometimes I leave the fish finder on for couple hours before starting the engine.<br />Just a good idea to throw the battery charger on the engine battery every once in a while at home.<br />I also have solar panels on my engine battery and my trolling motor batteries, so that helps too.
