Ep.65. Electric boats & Lithium batteries

Electric boats have come of age because of improvements of lithium battery technology, and lithium is now available for marine battery installation. Marine lithium batteries, battery management system (BMS), voltage considerations and more are discussed here. The discussion with Jean-Marc Zanni will interest anyone interested in installing lithium batteries in their marine vessel. As a bonus, some video clips of powerful electric outboard engines and electric hybrid marine systems. Links to full videos are below. - Sorry about the poor quality zoom images; DSL internet in Northern Ontario is pretty bad - This video and all the videos I have made are dedicated to my father who passed away today (Dec. 31 2020). They were made for him. *****LINKS***** Jean Marc Zanni and AE&M Engineering http://seariouspower.com/ MG batteries https://www.mgenergysystems.eu/ ******CHECK OUT THESE VIDEOS ON ELECTRIC BOATS****** Goldfish Tender: https://www.youtube.com/watch?v=e0Ln10bV7AE&t=28s Campion electric boat: https://www.youtube.com/watch?v=yg1aH55cxow&t=3s Hybrid electric motor yacht: https://www.youtube.com/watch?v=eX8c3UB22dE&t=6s Ian Bruce's hybric electric boat: https://www.youtube.com/watch?v=U2C8VOhWOns&t=20s MG batteries in Silent yachts https://www.youtube.com/watch?v=nVG5SMwxLYY Note: We are not sponsored by any products, and not by any products shown in this video ***Music by Epidemic Sound*** A Bitter Love - Sven Karlsson (Intro music) Best for you - Dayon Lost in Atlantis – Smartface (end music) ***Web site*** http://www.biotrek-sailing.com 0:00 Intro 0:50 180 HP electric outboard engine 1:18 Serial hybrid electric propulsion 1:35 Ian Bruce’s electric runabout 2:23 Introduction to Jean-Marc Zanni 3:32 Silent yachts 4:48 MG lithium batteries 5:51 Integrating MG batteries with Mastervolt 6:23 Mastervolt systems need a bridge to communicate 6:48 Batteries need to be charged to proper voltage 8:21 Saving weight on a catamaran 8:35 Table comparing weights for different batteries 9:53 Project with Nordhaven 65 10:52 Lithium batteries on smaller boats 11:18 Lithium batteries and safety 13:07 Other brands of lithium batteries 13:30 Internal or external BMS? 15:30 Batteries must have authority to open the contactor 16:01 Limitations of an internal BMS 16:50 Dealing with high peak loads eg winches 17:30 Jean-Marc is US distributer for MG batteries 18:14 Different boats with MG batteries 18:50 Risk of water penetration in MG batteries 19:30 Limitation of Tesla batteries for marine indications
