HI Guys, 

Just wanted to put this message out there for advise.... Does anyone have a Victron ESS setup, using a Lithium battery from LBSA? I have a ESS setup and was using the system with lead acid batteries for months with no problems. I thought I would upgrade the battery to Lithium... now I have a charge problem with this battery. I have set all the settings as suggested using ve configure. Bulk/absorption  56.00V /1 hour, float 54v. I am using the BMS from the battery to control the charge and DVCC is on and the rest off as suggested,  If i use the battery till about 80% SOC, then go back to mains, charging is normal, bulk till about 98%, absorption till the battery is 100%, then the inverter will jump between bulk and absorption at random, no set time to this and never goes to float... is this normal? Then with the battery at 100% it will drain till about 95% the next morning, "no power failures", once the BMS detects 95% SOC it will start the same process again... If I look at the battery details on the GX, the battery charge state is "blocked"  because the battery is at 100%, should the BMS then not comment the inverter to go float and keep the battery at 54v? Does anyone know if the battery is full compatible with Victron? 

 

thanks

Might be the specific Victron model not geared for lithium,inverter might require software upgrade.
