Need Help
 

:hi: New here and can't figure out how to post a new posting... Figured this out I think... Any ways if you can help would be appreciated. Just acquired an 86 V 20 and starting to work on and need some help there also... Am also going to change the battery location so will keep up with you on your progress

Didn't think about trying to turn them, I was worried about to much weight on one side. Must be okay if you have two battery's and oil tank.

Also think I'm going to add a solar trickle charger on the hard top ,for the days I troll a lot ,to help keep them fully charged

Fished the last day of rockfish season ,volts were getting under 11,starting having radio issues.

Project done. Turned out nice. The only thing is the weather has been cold, had to get dude up the street with a heated shop to finish it.
As soon as the weather breaks, I'm going to work on the solar charger and see if that is really going to work.

A 100 watt solar panel, if mounted flat, will give you 5 Amps charging in the middle of the day. Put on two of you have room. It will help some. An MPPT charge controller helps put the max into the batteries. I use a Tracer type from Amazon. These were made for solid wire for street lamps. You need to solder the ends or crimp ferrules to the ends of stranded wire for mechanical strength, otherwise the screw terminal trash the wires ends.

You might want to install a Victron battery monitor to keep track of the power going in and out.

I love solar power. I put 830 watts on my camper and it supports an electric blanket. Boats have less space but I would still have as much as would fit.
