DIY lithium batteries can save you thousands! Part 1 Episode 37 #catamaran #refit

One of the biggest and costliest project in many yacht refits is new batteries. These days, most battery changes are by people moving from standard AGMs to Lithium, or making the change to a higher native voltage from 12v to 24v or 48v. We are making the change to a native 48v system and increasing the storage capacity to 55kwh in an effort to increase our cruising independence. Commercial marine batteries tend to come in standard sizes and are limited to 100ah or 200ah. Going the traditional route would require us to expand the space that holds by batteries by double or triple the physical space. Instead, we've opted to assemble the batteries ourselves, allowing us to choose the total voltage and capacity with a lot more flexibility. We imported CALB cells directly from China, and are doing the work to DIY our battery bank. In the end, we will get significantly more storage into a smaller space, for about 1/3 of the price. This is part one of the process. When we finish showing the entire process, we'll provide a dedicated page on our website with all the nitty, gritty details including the entire planning and importation process as well as the installation.

A couple travelers out chasing the horizon, meeting the people, and capturing it to share with you. We've chosen to Roam the world by boat because, let's face it, the most interesting path is rarely a straight line. As we learn to let go of our American drive to finish, and embrace the meandering routes across islands, oceans, continents, and people, we hope to gain a better sense of our world and our place in it. The path won't always be comfortable or easy to find but, it will always #roam Here's an index of the video in case you want to see something specific: 00:00 Heading out it the dark 00:40 Intro to Us 00:56 Car talk.
