Victron SmartShunt 500A/50mV Battery Settings - Sterling Power 120Ah Lithium

Hi,
I was wondering if anyone has a similar setup that has the battery settings (obviously I know the capacity) for the Shunt that is working for them?

The charge parameters from Sterling are;

  1. Max Charge - 14.8V
  2. Recommended - 14.6V
  3. Float - 13.8V

The Shunt rarely (if ever) shows the correct SoC once the battery begins to discharge and there is a rabbit hole of information on the WWW.
Any advice and pointers greatly appreciated.

Thanks

Confirm:

Capacity is set correctly

Peukert is set to 1.05

Charged voltage is 0.2V below absorption (solar charging) or float (AC charging)

Tail current is 5%

If using aux input Temp, make sure temperature coefficient is 0

If none of the above resolve it, remove all devices from load side of shunt and conduct zero current calibration.
