After Reading all the FAQs here i’ m still not sure, where my problem is…

my configuration (Van, 12V)

Bulltron Lifepo 210Ah battery

Victron Smartsolar MPPT 75/15 and a 110W Panel

Victron Smartshunt 300A

Victron BlueSmart IPP 22 12/20 charger

Problem: after a few weeks without charging, only solar the battery was around 60% according to the Shunt.

charging let the shunt went to 100% after “filling” the Ah, he was showing as missing. This was at a current of 13.5V.

Since 2,5 hours the Charger is still loading with 17A and the Shunt rests at 100%.

My settings:

The Charger and the Solar Charger settings are Standard set to Lifepo.
