Works.

It is nice of Current Connected to provide this custom cable. I DIYer would have a hard time doing this themselves. That said, I'm not sure if the Cerbo is getting more info than it needs or conflicting info from 2 different sources. What should take priority, this BMS CAN RJ45 info or Info coming from the Smart Shunt? I would think Smart Shunt, but have no data to back this up. I feel I am messing up the works with this intfo coming from NON-Victron Batteries. But who knows. I'm gonna try to sort it out. My Cerbo can read Voltage and SoC via this cable, but SoC is likely bogus info.. from my recent experience.
