2 x 150ah Victron SmartLithium batteries:
Battery 1
- Cell 1: 3.05V
- Cell 2: 3.04V
- Cell 3: 3.05V
- Cell 4: 3.06V
Battery 2
- Cell 1: 3.08V
- Cell 2: 3.09V
- Cell 3: 3.00V
- Cell 4: 2.97V
System is saying 71% state of charge. And the A-SL11 under voltage alarm is saying "battery full discharged, cell voltage below the allow to discharge cell voltage set in the app.
The manual says:
4.8.2. Cell under voltage pre-alarm thresholdWhen the cell voltage drops below this threshold, the pre-alarm signal is sent to the BMS. The purpose of the pre-alarm is to warnthe user that the system is about to shut down due to undervoltage. For more details see chapter: “System design”.The default value is 3.10 V and the range is 2.80 V to 3.15 V.
Is it correct that my system is at 71% SoC? To use the system below 70% I can just change this Cell voltage disconnect feature down to 2.80V? And are the Cell 3 and 4 readings anything to worry about?
