Solar flex

Does the system need to be turned off when not being used, just put in lithiumí batteries in , donít want to overcharge them or is it controlled by victron system so they donít overcharge?

You don't have to worry about over charging. The victron and internal BIM will take care of it.

That's the beauty of lithium batteries. They have a BMS that prevents overcharging. Even if it's freezing they will stop charging to prevent damage. Now if they don't have a BMS then I suggest you get one.


What batteries did you get?

X3 on Victron MPPT and battery's internal BMS (Battery Managrment System) taking care of your lithium batteries for you without concern.
Do suggest getting the specific charge parameters for your batteries from either data sheet or directly from the manufacturer. Those parameters will need to be inputted into your MPPT to get full benefit from your new batteries.

I turn off the charge controller when parked in covered storage. We have the 400i package with the factory dragon fly lithiums.
