The two batteries are connected together as a single unit for the system, which doesn’t recognize how many batteries are plugged in. Is this correct ? Even if there were an issue with one of the consumers, why would one battery remain charged (and balanced) while the other is completely empty? This has occurs with a BMS and a battery protect that is setup with the lithium profile.
The entire system is set up using the default Lithium-ion profile from Victron.
My initial mistake was to use 2 batt instead of one 25V, but this is a different story
Indeed, I’ll send it back for the warranty.
Just for my records, what is or could be that clicking noise ?

I don’t have a lot of diagnostic info to work with from your system, so all I can do is swing at possibilities, which isn’t very useful, and most likely is wrong.
Did you take any screenshots from VictronConnect? Can you connect to the Lithium Battery with VictronConnect when you put the 12V on the 1V battery terminals?
An explanation for how once battery is at 1V with the other at 13V is a sudden mechanical failure, but I am not saying that is what has occurred.
It would be a lot easier with a full wiring diagram for your system.
I don’t know what that sound is, I haven’t heard that before.
I’m unable to connect—the battery isn’t showing up, and I don’t want to damage it further. I also don’t like those sounds, which is why I’m not charging the battery.
Here’s a picture with a quick overview of the system.
It doesn’t properly represent how the system is wired, and if it isn’t done correctly could definitely lead to the failure.
If any of those loads or charge sources aren’t connected correctly it could fail. There are many possibilities for an incomplete connection as it can be quite complicated with so many parts, which is also why I am guessing they weren’t included in the design, but they must be.
Probably the most important thing to note is that the Load disconnect and the charge disconnects are different circuits, here they are drawn as one.
Hi @guystewart , indeed this is an important point, but the system was working for 1,5years. I have to check again everything and I’ll do a real schematics.
since everything is still under warranty.
