Voltage Spikes with Victron MultiPlus and Lithium batteries


I'm having issues where I see voltage spikes, most likely from the Victron MultiPlus.

I have seen this in two systems:

System #1:

  • Victron MultiPlus 12/3000
  • Victron BMV-712
  • 12x 100Ah 12V Lithium Batteries (Parallel, 1200Ah)

The system has been working without any issues, but I see the spikes as shown in the video below. I have read and heard mentions of cell imbalance, but I have high doubts this is the case. The batteries have been individually charged up to 100% SOC before tests.

System #2:

  • Victron MultiPlus 24/3000
  • Victron BMV-712
  • 4x 300Ah 12V Lithium batteries (In series, 600Ah 24V)

Same issues as mentioned above in this system. There are spikes of ampere and voltage, for unknown reasons. In practice, this does not affect the functionality of the system, but it does trigger alarms to go off, which is unfortunate.

I have been in touch with Victron experts, but with no clear answer as to why this is happening.

I'm very curious why these spikes are happening. Is there anyone out there with some knowledge here?

Appreciate all help!
