I asked the same question some days ago, but it seems like it was closed before it was answered, so I'll try again.
I would like to use my Cyrix-li-ct 230A for start assist.
The online datasheet for says I can: https://www.victronenergy.com/upload/documents/Datasheet-Cyrix-Li-ion-230-A-EN.pdf
However, the datasheet that came with my device does not indicate this:
This online picture shows two yellow cables (and one black).
My device only an outlet where I can connect the "Control cable for Cyrix 12/24-230", and thus only have one red (and one black).
As my picture show "VE Bus BMS", and the online shows "...V2", maybe I have an an older device?
Can I still use the red the same way as the one for Start assist in the online picture?
