Today I removed my 2 x 100AH lead acid leisure batteries and fitted 2 x 105AH Fogstar Drift lithiums.
The lithiums had been fully charged at home prior to fitting.
I have changed my Victron MPPT, Victron Smart Shunt and Sterling B2B settings/parameters to suit the lithiums.
Once fitted I checked the lithiums voltage with a multimeter, which showed 14.4v.
There was a bit of solar, 6 watt from my 2 x 100 watt panels, so I figured that was what was raing the battery voltage.
But my shunt app and MPPT app both showed battery voltage as 13.4v ?
I turned on my voltage meter, which is totally independent being wired direct to the batteries, and it also showed 13.4v.
I tried another multimeter on the batteries which showed the same as the first multimeter, 14.4v.
Both Victron apps, smart shunt and smart solar, still showed 13.4v.
Yet again I was unable to connect to the Fogstar app ( I have been unable to connect to the Fogstar app since getting the batteries) and this time I also couldn't connect to the Xiaoxiang app which previously had worked, so I couldn't see what the battery apps were saying.
Does this voltage discrepancy sound correct ?
