Building a 280AH 12-volt house bank that will reside year-round inside a sailboat dry-stored in Puerto Penasco, Mexico (northern most section of the Sea of Cortez). As summer temperatures are routinely 100+ degree temperatures, I'm exploring cooling options. One consideration is to build a...

Thanks for sharing the diagram and helping me sort though this conundrum. I so wish I had brought a diagram and inventory of Concordia's electrical system. What your diagram does is remind me that my system has is simplicity crammed into some complexity that most boaters would go, "huh?" For...

Also looking to change out the house bank in our boat with a 400ah system. Mind sharing your full build specs?

Folks ... While my thread may be betters suited for the beginner's corner, fellow boaters may better understand my challenge. We have been commuter cruising our 43 foot Cape North Cutter Concordia in the Sea of Cortez for three years now. The first two years we were able to visit the boat twice...

I leave the cabin fans on to circulate air within the boat during storage. It also places a small load on the batteries, which are fed by three 100w panels. The radio is mostly just to add another load on batteries (though I don't know if it matters for the wet cell batteries). As for the...

In the middle of summer the night-time low (at about 6 a.m.) is about 10 degrees less than the daytime high. Humidity will reach 90 percent throughout the summer. Thanks!

They have definitely grown up. Cabo and La Paz are not what they were in the 80s. I think I'll go the disconnect route and sort through more frequent trips to recharge.

That is a genius solution. The version he displayed on the video is available on ebay for under $30. Not sure if the energy demand can be accommodated the planned house bank. Working current: 10A - Working voltage: 12V - Power: 72w

Very much want to shift to LiFePO on Concordia, but the more I learn the less I feel ready. To do it right, I will need to change a majority of the system infrastructure. Swapping out the flooded cells for the LiFePO isn't reality. I really appreciate your help walking through this. You haven't...

Nibs - Yes. The golf cart batteries have been compromised. I'm fully expecting that a substantial amount of the plate will be exposed when opening the fill ports (in the past, they were just below the surface). Don't recall if I can set the Victron to a lower voltage. As for a full disconnect...

Ug this is getting complicated. Hadn’t gotten to the alternator/charging issue. For the DC to DC charger, assume I would need a unit that handles 50 amps. A 40 amp renogy, for example, would not. Now, this brings up another topic: the starting battery. Does it too need to be Lifepo or can I keep...
