FAQ: Lithium Battery Monitoring, Electrical Repair Kit, and 24V vs 12V DC

This is a series of questions asked by our patrons about Lithium batteries, solar charging, and electrical sailboat items in general. This series of videos covers the following questions:

What are some of the heavy draw electrical items on Delos?
What can be run directly off the batteries and inverters?
What tools, meters, and connectors do we carry on Delos?
What resources do we carry for troubleshooting electrical problems?
How do we monitor our batteries on Delos?
What fridges and freezers can you run off solar and wind?
How much does Air conditioning draw, and can we run it off our solar?
Do we power our laptops with a DC to DC converter or via the inverter?
Is it possible to maintain a 48V battery bank?
Is a 24V DC system practical?
What are the benefits of a 24VDC system?
Solar arch- Why don’t we have our dinghy on davits off the solar arch?
What is the make and model of our inverter?
Could we incorporate water collection into our solar panels.
Is there a difference in the taste of desalinated water?
Have we ever had issued with the solar panels in high wind?
Are the lithium batteries physically the same size as lead batteries?
What about safety with Lithium batteries?
Are solar panels cost effective?
How have prices for solar decreased since we first installed them?
Are Lithium batteries cost effective?
What wire gauge should you use for a solar charge controller?
Pro’s and Cons for a solar arch?
Can we run our dive compressor and water maker off solar and an inverter?
How much more power do we use on Delos than a “normal” cruising boat?
Is a Hybrid Electric drive a real option for a Bluewater cruising boat?
What would it take to get rid of a diesel generator?
How big is our fridge and freezer compared to a house?
How much does our entire arch and solar panel setup weigh?

System Overview for solar, wind, and lithium batteries – Electrical Boat Tech

A compete, high level view of the electrical system on a modern cruising sailboat. I put together a gigantic diagram and talk in detail about each component of the system, and how everything interacts to supply the electrical demand on a modern cruising sailboat. Topics covered in this video:

1) A project recap of the installation of our LIFePO4 Lithium Batteries, inverter, battery monitoring system, and switching to electric induction cooking on a sailboat.
2) A complete walk through of the electrical system of a modern cruising boat. Starting at the power sources (wind, solar, hydro, generator, and dock) Brian explains each part of the system and how everything works together.
3) We discuss the role of charge controllers and how important of a role they play.
4) How much power can we generated with wind and solar?
5) Just how noisy are wind generators?
6) 1 Year review of our Induction Stove and Electric oven and how it’s worked out.

Installing Lithium Batteries on a Sailboat!!! Part 1- Sailing Vessel Delos

Our Mission- Get rid of propane and move into the 21st century with induction cooking! We install a bank of Lithium batteries, a big ass inverter, and an induction cooktop. This video covers the installation process and what tweaks we made on Delos to get the system working.

Check out for some FAQ and more info on what we installed.

I think I will do a Part 2 that covers the rest of the configuration of the charge controllers, and what we do to replace the old propane oven. Stay Tuned, and thanks so much for all your support that makes these videos possible 🙂

Hope you enjoyed, and learned a little something like I did. For more of these types of videos please give the video a LIKE! Or buy us a beer ha ha 🙂

WATT the hell is an amp hour?

If you’ve ever wondered what the hell an amp hour is, how to calculate your power usage onboard, and what it means with respect to battery capacity then this video is for you! If you like this type of content and would like to see more please support us at .
