Hi, i'm developing a full electric propulsion plant for an e-boat (scheme in the image attached).
I have a doubt: i'm gonna use a 12V service battery to power on board hotels, feeding the service battery with current with voltage scaled by the DC/DC converter (the Victron Energy Orion Tr-48/12-9, as you can see in the scheme). The problem is that the DC/DC converter could continue to feed the battery even when the battery is fully charged, leading to overcharge and its dangerous consequences. How could i solve this problem?
