BMV 700 showing Volts but no battery %

All my negs. go to correct terminal of smart shunt-mppt inverter fuse box. Smart shunt neg. to 200ah LifeOp4 battery.

BMV 700 display shows 13.14 volts

0.0% battery. Battery graphic is outline only not solid.

All parameters are set for LifeOp4.

Battery terminals read 14.33volts with meter

What do you have? BMV-700 or SmartShunt?

After the installation you have to do a full charge cycle to synchronize the SOC to 100%.

Can you show us the settings?

So I connected VE Bluetooth to bmv 700 (not done before) & entered % value for 13.14 at 97% (guess) & all good. I think I must have reset everything when I removed battery to charge via shore line 240v

(v cloudy recently ). I left for 2 weeks with no power draws, mppt still charging & battery percentage was at 4%.

Bmv 700 with the shunt, not smart as I said.
