Lithium battery

Just wondering if anyone could take a look at my Bmv700 settings and my current read out of my 720ah lithium battery install, does it look OK.Screenshot_20240730_114447.jpgScreenshot_20240730_114434.jpg

Looks OK, you may want to set the tail current to 4% as charging can stop before this depending on charger settings.

Thanks for taking a look, the 12/3000/50/120 multiplus is set at it's lithium battery default as are the 3 mppt units, 2 x 100/30 & 1x 75/15, although I have dropped the absorption voltage on the multiplus to 14.2v.

The default Victron Smart lithium profile gives a 2hr absorption so should go below 2% tail current. If your batteries are not Victron double check that this is acceptable and adjust the settings If not.
