This just proves the weak link is the BMS. I had the honor of replacing the BMS in that exact model in a stack of 3 batteries. Luckily it was on the bottom shelf so I could pull the monster out onto the floor to get access to the lid. The lid is sealed shut but with persistence it opened. I was working with their tech support and following their instructions. I disconnected it from the other two that were in a parallel configuration before opening. Battery voltage was zero at the terminals. I did voltage checks at various checkpoints to confirm it was the BMS at fault. Relion sent a new BMS which I carefully installed and it has worked fine since. Had I seen this photo first, I may have not been so eager to see the inside of that battery.
