Battery life

I have a newish jeanneau and I get random over volt warnings from the jeanneau panel but my victron battery moniter shows no problem. In fact if you compare the volts from jeanneau panel and victron Bmv they are never the same, the victron has a very steady slow change in volts when various power hungry devices cycle but the jeanneau panel shows rapid swings up and down in the voltage so I don't think it's very accurate in the short term when power consumption is changing.
My advice would be buy a cheapish battery monitor, lots out there and some don't even need a shunt, so simple to install, and this will give u a better idea the state of your batteries. Do bear in mind jeanneau uses cheaper sealed batteries that have a limited life and don't like deep discharges as much as some of the more expensive types.

The switch panel monitors are a crumby design I've found. They are usually attached somewhere far away from the battery so once you factor in the voltage drop they are off by 5-15%.
