Subject: Looking for battery/electrical ideas
Info: (5904 views) Posted: Thursday 2-14-13 10:19:24 PM
For the bay with occasional auto pilot, I use a 32 amp gel battery from West Marine, though I have had to replace it 3 times under warranty. It's fine now and nothing has changed in my electrical system. I think it was a bad batch. For 2-4 ocean days, I use an 80 amp lead acid battery with solar chargers. I also take my small 32 amp as back up.

I'm impressed with Roger's outboard alternator. I wonder if I can do that off my two stroke.
