Camper with two Volthium lithium batteries, Victron battery monitor and solar controller. Below is a screenshot of the Victron app. Notice it shows 13.11V on the batteries and a 96% charge. The chart I have been using shows 13.1V with a capacity of 40%. Why the discrepancy?
We just camped 4 nights in a row with no discrepancy, now that we are home and the camper parked I am seeing this
Wrong settings in BMV
Read the FAQ linked in the sticky post at the top of the DIY category. Its title reflects your observations, your shunt is probably not set correctly as the symptoms you see are the normal result of this.
This charts are garbage.
13.3V is the idle voltage of a fully charged battery.
With a load of only 3W you should still have a voltage of around 13,3V
Did you do a full charge cycle to synchronize the shunt to 100%
What are your settings?
Only 4,5h left with a load of 3W?! What is the capacity of the batteries?
Here are the settings
Missing info, what is your absorption voltage. It would be easy to have 13.81V with little charge current trigger a synch to 100%. The info is in the FAQ I linked, your charged voltage at 13.8V is too low, set it to 0.1 to 0.2V below absorption.
Charged Voltage should be 14.3, then everything should work
