The discussion here is always interesting but I wonder about the following. There are a lot of electric cars out there which are charged to 100% SOC every day, right? How do their BMS deal with it? How much of a problem is it really to charge to 100%? Are we overthinking the issue? I’ve posted elsewhere on this forum that I Have had installed an all Mastervolt system on my boat recently. Mastervolt has certified that the installation conforms to their specs but I can’t try it out since I can’t get to the boat in Spain. Based on the discussion here, I have told the boatyard not to plug the boat into shore power for now - SOC is 85% currently as shown on the MV Easyview Monitor. I suspect this is unnecessary and will follow up with MV for their official view. Will let you all know what I hear. Cheers. Joerg
