Battery consumption. It's a mystery.
Well, last summer I used very, very little power. So little that a seven watt solar power was my sole means of charging my battery and it never died.
This year I'm upping things. I'm sitting here organizing and packing, well. I'm done for the night, but I've got a LOT of lithium battery toys to charge. I know a lot of it is small. Camera batteries. A laptop. Ipad, phone. Bluetooth things.
Then I have the boat stuff. I've got a ray marine st2000 autopilot, I think I will use extensively, chart plotter, depthsounders, led nav and spreader lights, led interior lights and assorted boat electronics. Oh and a stereo with two speakers.
Battery consumption is on my to do list to learn, but I'm not there yet. Basically do you think I have enough of a system to work?
I have two gel batteries. I believe 97 amp hours each, a 50 watt solar charger, an alternator on my outboard and maybe a small generator. Let's pretend I don't have a generator because I'm not sure I do. Will my solar panel and alternator be enough, and do I have enough for my battery bank?
My thinking is that the solar will do a lot, and the rest I'll just have to be that guy that idles his engine on days I don't spend extensive time motoring to a new place. Maybe idle an hour a day? Is this a good base plan or do I need to start thinking about a fix?
