Hi the smart shunt was working well however, I disconnected the battery and reconnected it later and the shunt doesn’t update the state of charge. If I manually update the current soc as per the battery BMS it does not save the update and reverts to 100% charge. The connections appear correct. Any ideas?

You would have to wait for a discharge and charge cycle to re sync again.
There is a setting called keep soc on reset. That usually stops the bounce to 100% if there is a disconnect/ loss of power.
