Hi all, I'm new here and have joined due to the wealth of expertise you seem to have in your ranks. I also intend to be building batteries for a while so look forward to helping out too. But for now, I'm having some issues during the commissioning of my project..
I have purchased and installeda Batrium WatchmonPLUS (WM5), been through all the guides and confident I have it set up correctly. I have a 12S cell configuration, the cell voltages of which can be seen in the images attached. Also attached is the cell telemetry - from both images you can see there is a 0.19 difference between min and max cell voltage - so I've sent the bypass voltage to 4.12 to start to reduce this differential and the red bar above cell 7 indicates this cell is discharging.
It's clear that the Watchmon *thinks* it is balancing cell 7, however after many days of operation with no change to the cell voltage - it's crystal clear that it in fact is not balancing this cell.
Does anybody have any ideas what might be happening here? I'm talking with Batrium support however the time difference between us means I'm effectively getting one message per day each way so it's slow progress - and I don't feel like they really grasp the issue.
I suspect a faulty board, I hope not but can't see any other outcome at this stage.
