Simple Battery Float Charger

This will keep your battery charged when you car is parked for a long time. The solar panel needs to face South at about a 45 degree angle or so. If you have to run a long length of wire to mount your solar panel, just buy a cheap 18ga. Or 16ga. extension cord and cut off the ends. We got the solar panel and the charge controller off of Amazon and they are relatively inexpensive. Cheers! -DS

Good idea! This type of setup is also common for electric boat lifts as they often aren't near a power source. I see you are charging a marine battery which make me wonder if you are doing something similar.

I am convinced you are Bill Robertson from an alternate reality where he is more handy with electronics.

We set this up for my son’s camper trailer because he has a small drain on the battery. It’s been working great for about a year now.
