The AiLi monitor being discussed here, (as well as the various Victron monitors and most others) all use the shunt negative lead as the return for the meter power supply. They cannot be installed on the positive side of the battery.

Don't know what shunt monitor system you may have had problems with,
But the ones I installed, used separated sensing wires pair (shunt to meter), and meter power wires pair, worked perfectly with shunt in the positive main path,
Power for the meter/monitor should always come from separate wires going directly to the battery, to always supply and isolated power path, even better from a separate power supply and not the battery be measured
