Hi, I have a camper van installation with 5x 100 AH Eco Worthy batteries in parallel and I'm using a 2000 Watt inverter to power up my coffee machine. The coffee machine trains at average 110A and at max 160A from the system. The Batterie Pack should have a max current capacity of 500A but randomly the batteries are breaking down for a couple of seconds. It seams that the all BMS Cut Off at the same time. The system works sometimes stable and sometimes it breaks down. I’m not able to force a break down. The problem occurs independent of the state of charge. All requirements (e.g. Cable Size, conctors,…) are double checked and within specification. Any idea what causes the break down?
