Swapping From AGM to Lithium Batteries on a Sailboat
June 05, 2018 by Out Chasing Stars | Language: EN Play Time: 00:23:58 | SAILING YOUTUBERS
After 3 years of sailing on Starry Horizons, the time had come to replace our old AGM battery bank with something new. We were ready for Lithium.
Doing the swap over required almost a complete re-work of our 12v electrical system in order to do things properly. We installed a 720Ah 12v LiFePO4 house bank with a BMS and Distribution Control Board, upgraded to a 3,000W/120A Inverter Charger, swapped out MPPT Solar Controllers AND the alternators on our engines.
This was a serious project but we wanted to make sure we did it right. There are some issues around Lithium Battery banks that need to be addressed and in this video we talk about how we came up with a set-up we’re comfortable with as we sail around the world. Plus I’ll touch on some of the lessons learned through the whole process.
There’s a lot to talk about, so here are some links to specific parts of the video:

Out Chasing Stars
Welcome to Out Chasing Stars! We're Admiral Amy and Captain David and we're currently exploring the world on s/v Starry Horizons, our Fountaine Pajot Helia 44 catamaran. We started out (nervously!) watching our boat get launched in La Rochelle, France in October of 2014. Since then we've completed an entire world circumnavigation, sailing over 37,000nm, and documented it all here on YouTube. We started making these videos to show our family and friends what life was like on a sailboat, and we're still amazed that other people have also started following along. It's been so much fun to share our adventures and we love reading all the comments and support! There's a lot of world left to see so don't forget to check back in and subscribe! You can check out our blog: www.outchasingstars.com And of course, we're also on Facebook and Instagram: https://www.facebook.com/outchasingstars/ https://www.instagram.com/outchasingstars/
