This is on a RV with AGM batteries. The graph shows starting the generator, stopping the generator, then starting / driving the RV. Finally, the RV is plugged in to shore power.
Note that the charge current continues but the SOC immediately goes to 100%
Thanks for your input
Show us your Cofiguration for the Shunt/BMV …
Maybe a wrong Voltage and/or Current in there …
What is used for charging with shore power?
Steffen, charging is controlled by a Xantex inverter. It’s set to AGM battery. Note the charging current continues linearly…but the SOC jumps to 100%?
You have to check the settings for Voltage / Time / Tail current …
because this … some Picture of the Setting …
The translations are terrible 
Have a read of the FAQ on shunt jumping to 100%, which is listed along with many other FAQs for the DIYer in the sticky post at the top of DIY section.
Thank you for your solutions offered. Ron G
