BMV702 - Ah consumption / percentage loading not correct ? loading seems underestimated in

BMV702 - Ah consumption / percentage loading not correct ?
Our BMV shows correct consumption of Ah … BUT when we do load batteries with generator or engine the actual loading seems to be underestimated in Ah and %; after 1-2 hours loading the percentage changes suddenly from one sevond to the next for example from 94% to 100% .

What’s wrong? Can you help ?

P.S. displayed battery voltage seems to be correct at all times

Johannes explains the settings required to set up a BMV battery monitor shunt for either Lead and Lithium batteries. It's important to synchronise the charging and each setting is explained in detail including voltages, absorption and bulk battery charging settings.
