Battery amps
8 amp would be more sufficient for short trips , probably 7 hrs or 8 max . 10 amp for longer trips , maybe 8 - 10 hrs , and 18 amp can power larger 7 " screens all day. If you do long trips on the water , I would recommend at least a 10 amp battery as to reduce , or eliminate power problems . Also it us recommended to have a 3 amp fuse inline . A lot of helpful guys should chime in right about now . B
