Midpoint voltage on a 12v battery bank

Ok I’m sure the answer is already here but I can’t find it for the life of me!

I have 3 100AH batteries in parallel making a 12v 300AH system.

I’ve connected my midpoint voltage reading to the B2 side of the shunt and then to my middle battery in my bank on the positive battery terminal, everything is working perfectly except I’m reading 100.10% deviation and obviously the alarm is constant.

What have I done?

In a 12V system you don't have a midpoint voltage to measure.
This feature is for 24V or 48V systems.
