I am designing a 48v lithium installation for my boat. According to Victron, the batteries will have an absorption charge of 57.6 volts, but I can only find battery disconnect switches rated to 48 volts. What should I install? Thanks …
Not sure if you are referring to this switch exactly, but the datasheet says up to 60VDC
Thanks, I must have looked at an older datasheet.
I’ve had no issues at all using Blue Sea Systems 6006 and 9003e switches on 48V systems. That 48V rating is a “nominal” rating and Blue Sea will NOT say whether or not those switches are rated to at most 48V or if rated for 48V nominal. I don’t really blame them I suppose. But I can tell you I’ve not had any issues. Just like any other DC disconnect; don’t switch under load.
