I am trying to protect my alternators while charging lithium batteries. I have seen this document:
This states that if using the mentioned cable the BMS 12/200 can be used as a current limiter. in this video: https://www.youtube.com/watch?v=ZyIJRjJtCR0&t=197s it is mentioned that up to 200A can be used.
I do not have the VE.Bus unit. Can anyone explain to me what voltage or signal that is supposed to be sent through the mentioned cable. It looks like the red wire is 12V + , but what is to be sent through the yellow cable, connected to the charge disconnect port of the VE.Bus.
