Voltage of new lithium battery keeps dropping

[Brum2611]

Hi,

I build my electrical system about 3 weeks ago, and since 1 week i’ve been slowly losing voltage until my whole system shuts off until I charge again. Graph included.

From what ive read it could mean a dead battery, but it a completely new lithium battery.

For now im charging only from the grid, planning on adding solar panels.

Anyone know what is going on?

More info required, what size battery, what are your loads, are you sure you are getting to 100% with charging, what charge rate do you use. Default SmartShunt settings may not be right and you could be indicating 100% before the battery is full. What are your SmartShunt settings. Do you have any loads connected to the battery negative directly.
