When my battery charger is off, my lithium bank reads 12.4 volts. As soon as I turn it on, the Victron IP65 shows 13.8 volts and goes to a one amp charge. Float? If I turn off the charger, it goes back to showing a 12.4 volt charge on a second meter. I assume this is has something to do with where my cables are connected but… I am replacing an IP44 and it’s wired to the same terminals as before. The IP44 read the battery correctly and would throw 40 to 50 amps at that battery level.
