I need to monitor the status of charge on two Victron 150 ah Lithium batteries. Since the 12/200 BMS controls the system on the low side, where can I place a battery monitor shunt so as not to interfere with the BMS12/200 function? Most battery monitors require the shunt to be placed on the low side, negative side. BTW, unless I am mistaken, the bluetooth/victron connect app only provides voltage, no state of charge information.
