I added a 280ah fogstar battery to my 200ah ks one. Ks was 100% but fogstar only about 82% charged so I expected solar to kick in and start charging it then once at 100% go to float etc. then I could reset shunt to 100%.
Both shunt and solar are victron with 400w panels, it's cloudy but I would expect about 5 to 8 amps normally.
Do I need to somehow reset the solar controller to recognise the 2nd battery or something?

Someone with more experience than me will answer soon, but I didn’t think you should’nt mix different capacity batteries, but whether that would cause your problem I don’t know !

You can with lithium according to some videos I've seen and Advice on here but lead acid should be the same.

Maybe the new fogstar will settle down after a few charges and it may sync with other hardware better.

I have found if my Victon is on float, turn off the charging in the app and then switching it back on makes it revert to bulk charging.

Yes I think it's going to need a few cycles but just want to get it full for now.

Id have thought if the batteries are wired in parallel that they would gradually move to the same charge state the regulator won't know the charge state of the batteries separately . Hopefully someone on here who has done similar will answer soon

Did you turn the solar off when you added the battery..? You have to let the controller “see” the batteries before the solar…
