I came up with a weird idea. Or maybe everyone does it and I haven't noticed.
I want to use a plug-in battery charger, not sure which one yet, connected to the PV inputs on my Victron MPPT 100/30. The reason for this is to be able to use the charging profile of the Victron to control charging of my Dakota Lithium batteries. I want to charge them to only 80-90%, as I have learned that this should increase their lifespan. I believe most LiFePO4 chargers will not stop charging until +/- 100%.
I could try to find an adjustable LiFePO4 charger, but the Victron is already there and designed to do what I want to do. I would switch off the breaker between the panels and controller when using the shore power charger. I know the charger will also have to be able to put out high enough voltage to get the batteries to the desired SOC.
I found a couple people online talking about doing this and saying it's a good idea and will work, but there is some really good solar knowledge here, so I was hoping for some input on this.
So what say the (obviously) more solar-savvy members about this?
Thanks!
