Ep.64. Marine batteries: Marine electrical systems pt.2

Pierre explains marine batteries and the lithium batteries that we have on BioTrek. He provides general information about different batteries including their cost, weight, and performance. There is a menu below to skip to the sections of interest. This is a highly technical video and we will be back to sailing videos once BioTrek is launched in the spring. _Links_ Jean Marc Zanni and AE&M Engineering http://seariouspower.com/ MG batteries https://www.mgenergysystems.eu/ MG batteries in Silent yachts https://www.youtube.com/watch?v=nVG5SMwxLYY 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 Information on battery sulfation https://www.youtube.com/watch?v=IRHR9EaxSgE https://www.youtube.com/watch?v=_UT0lW4q-XM Note: We are not sponsored by any products, and not by any products shown in this video *Music by Epidemic Sound* A Bitter Love by Sven Karlsson (Intro music) The hot seat by Philip Ayers Lost in Atlantis – by Smartface (end music) *Web site*: http://www.biotrek-sailing.com 0:00 Intro 00:36 Drone shots of the Otonabee river and our airbnb 01:19 Pierre’s background in flying and sailing Tornados 03:50 Electric outboard 180 HP 03:56 Goldfish tender electric outboard 180 HP 03:03 Campion electric boat 04:23 Serial hybrid electric systems 04:41 Battery safety 05:08 Energy density 06:04 Battery volume 06:15 Charge and discharge limits 06:53 Table comparing different battery types 07:19 Voltage limits 07:37 Battery sulfation 07:55 Never exceed limits when battery charging 09:16 Cell balancing 10:56 Recap on energy storage and safety 12:32 Regulating a 48 volt AGM battery bank 14:15 Common battery facts table 14:51 Fusing 15:27 Opening and closing contactors 15:48 Pre-charge circuit 16:20 Lisa’s 26 ft electric sailboat 18:11 Table comparing 3 different battery types 19:00 Battery cost 20:16 MG batteries 20:42 battery weight 21:28 Weight per usable kWh 22:26 Why we chose MG lithium batteries 23:43 Interview with Jean-Marc Zanni 26:23 Drone shots of our airbnb
