Fully charged 12 v batteries should be 12.7 volts whether cranking, deep cycle, or dual puropse. Just like the chart that wrench posted.
I am running the biggest battery that I could find, North Star X2. It is the only one I could find that would support my electronics and hold enough charge to make it through the day even if I weren’t running live well pumps.
Wrench is correct about the voltage shown. Unless you have been out all day and not running your engine to build the battery back up you are too low. I try to never let my battery get below 12.4 volts. When it does I am going for a ride.
I don’t know anything about that stator stuff but you should have 12.7 volts when your battery is fully charged.
I took my neighbor to Stockton today. We threw spinner baits (no love), jigs (no love) and shaky on my new standup jig (lots of love). We caught 20 lmb and 1 smb. I had 9 keepers from 2-2.75 #. My neighbor had 4 keeper lmb and a 2.5 smb. He lost 4 keepers on the way to the boat. Worm color didn’t matter. The fish were on windy spots from about 8-20’ deep. We tried a few brush piles and couldn’t get bit.
My advice is narrow down your targets. Don’t try to go after all of those you named. Get baits specifc for your target species and work to learn about them and how to catch them.
What kind of changes? I make lots when I am developing a load, amount of powder, grain of bullet, type of primer, etc until I find out what works best. Then I get the scope zeroed in and leave it alone.
