Smart Lithium battery suffer significant voltage drop long before hitting the max discharge current.

I have a 330Ah Smart Lithium battery in my camper van. When I turn on the induction cook top, the Smart Shunt shows a current somewhere between 110A and 120A. This is way below the 400A "maximum continuous discharge current" listed on the specs. However, the voltage reported by the battery itself drops below 12V in a few minutes, eventually causes the MultiPlus Compact 2000 inverter to shutdown.

What can I do so that I can have sustained 100+A load on this system?

Thank you.

@Jia Pu what was the battery Soc? Voltage when load started? Last time Victron Connect reported "balanced"?

What lengths and cross section of cables do you have between the battery and the inverter?
