Midpoint alarm confusion

[Kevindstone (Kevin)]

My smart shunt throws a midpoint voltage alarm even though the measured midpoint voltage is within tolerances.

4 battery parallel wired with diagnal power and grounds. Aux probe connected to positive terminal of third battery main probe connected to positive on battery one

Deviation calculated at 99% when it is actually less than 1%

Mid point power is really intended for the higher voltage systems - 24 & 48V. As pointed out, it should be 50% of the nominal pack voltage. You can’t get at that with 12V batts wired in parallel.

Yep i was confused, thanks for clearing that up.
