How do I configure 2 BMVs connected in parallel to a battery bank?

Do I have to double the Shunt Current on the Misc menu or do I have to make it half? Do I have to change the shunt voltage as well?

A bit more info please , Why are you wanting 2 BMV units connected in Parallel.


are you connecting two BMV displays to the same shunt or are you installing two complete units inc the shunts


just wondering why thats all - as its highly unusual to parallel shunts

Finally, two BMV's can be connected in parallel if the shunt current on the Misc menu is double.

Ok now I understand...but like Matthias wrote: best to put them in series...or..

connect two 'shunt pcb's' to one shunt.

Do you mean, using an RJ12 splitter on the shunt and connect to monitors on the splitter? Can I connect a BMV 700 and a BMV 712 on the splitter or must they be identilcal. Of course I will use the shunt of the BMV 712.

No, you can't split the RJ12, that will definitely confuse the ADCs.
Either use two shunts in series or one shunt with two PCBs on it.

If I understand you correctly you have to wire both shunts in series not parallel.
