Two MultiPlus in master-slave config and Two-Signal BMS Support

Hello,

I'm using two MultiPlus 12/3000/120 16 in a master-slave - configuration connected to an other lithium battery and BMS.


Do I need to connect the BMS signal (allow to charge -> Aux IO / allow to discharge -> TempSense) to the MultiPlus master only, or is it need to connect the BMS signal in parallel to master and slave inputs and do I need to load the 'Two-Signal BMS assitant into master and slave?

Thanks in advance and b.r.

Load the assistant into all MultiPlus'. Connect the BMS wiring to one of them. I'd like to connect the BMS signals to the Master one
