I just bought the Victron 300 amp smart shunt and iv been watching a couple videos on how to connect it, but they only show it being connected to maybe one or two battery’s. I have the 100 amp Victron charge controller, charging all 4 liFePo4 battery’s with the the positive cable on the bottom battery and the negative at the top for even charge distribution. I’m not sure if that means anything but I want to make sure I have enough
detail here. I figured the smart shunt would just go in between the charge controller and first battery and I would just set the battery capacity in the app as the sum of all 4. Any advise would help!
Make a busbar, connect all battery
minuses and the shunt, then go further from the load/charger side of the shunt
See this diagram. Where it shows one battery negative connected to the battery terminal on the shunt, connect your 4 battery negatives. Everything else connects to the load side of the shunt. Best practice is as said above, connect the 4 battery negatives to a bus bar, then to the battery side of the shunt.
