So two 12v 200ah Victron Smart batteries were installed in a complete system with Lynx BMS and sent on its way.
I was contacted about a week later because they were getting a low voltage alarm and the system was not shutting down as it should.
I checked and rechecked the wiring and it all seemed fine.
I swapped batteries and it all seemed to work and I have not heard from them since.
Assuming there was an issue with the batteries I took a hard look at them.
They both recharged just fine but then I went to put them back in another system for testing and realized that the BMS leads on one of the batteries was swapped.
This is how they are supposed to look

But one of them looks like this

I don't know if they are switched internally or if they were just put in the wrong slots on the battery case during assembly.
I can't help but think that this is why the BMS never got the signal and thats why it did not shut down.
Anyone have any input on how the communication works between the BMS and the batteries and if this would wreck that?
