I have a 280Ah LifePo4 with a Daly BMS and a Victron Smart Shunt along with a Victron Blue Smart Charger i have just been charging the battery and have noticed the Smart Charger app and the Shunt app are both showing 14.2 v whilst the BMS app is showing 13.3v i have also tested the battery with a volt meter which reads 13.3v also, doe anyone have any idea why the difference in voltage
