Have you seen this > [@"Low Battery (Victron) and"Total Voltage Fault" (BMS)](https://community.victronenergy.com/t/low-battery-victron-and-total-voltage-fault-bms/19941): > > My installation: Multiplus II 48/10000/140. Battery Tewaycell Lifepo4 16S (Pace BMS) 15kwh, 308 Ah (in Cerbo displayed as 290 Ah), Cerbo GX and system runs with ESS. For a few days the system continuously gives alarm Low Battery by Victron and the BMS gives error message “Total Voltage Fault” and switches off the battery (all 16 cells have 3.35V). The battery is connected via the Cerbo Canbus and Cerbo communicates with the battery. In the Cerbo the battery is displayed as a Victron battery w… I guess theres communication between the BMS and Cerbo? So i guess the battery voltage that is reported in VRM is coming from the BMS directly, at 52.83V. The smartShunt however reports 53.28V. Since theres no current flowing, that voltage difference to me is way too big. I guess you have a bad/loos connection somewhere, some contact resistance or similar issue. If theres no current flowing, then the voltages should be nearly equal. Also double check them with a multimeter --- _[View the full topic](https://community.victronenergy.com/t/lifepo4-battery-charge-problem/43243)._
