I'm using the VictronConnect app to program my MultiPlus 12/2000. Under the charger settings, there's a "Lithium Batteries" option that I want enabled. I am able to toggle the switch on, but each time I exit the app, the switch by this option reverts to 'off'.
How are you connecting to the MultiPlus with VictronConnect - via Bluetooth or cable?
Connecting the VE.Bus Inverter/Charger to your device requires an MK3-USB for configuration mode, or VE.Bus Smart Dongle for status mode.
There are also minimum Multiplus firmware requirements for this to work, upgrade to the latest FW if you have not done so already (only do this if you are confident as you will loose all configuration settings - normally only a dealer or installer should do this and you may need a password)
Also, a lithium assistant might be required to be loaded to the MultiPlus first, if so then you would need to use VE.Configure for this.
Refer to this online manual for further information about using VictronConnect with a VE.Bus (inverter/charger) device;

I have the same issue with my Multiplus 24/3000 50-70 120volt using MK3. Not really sure,but I think Lithium means the Victron Branded Lithium batteries. Have you tried the LiFePo4 option?
Same issue here on a band new Multiplus 24/3000 50-70 120volt using MK3. Before I fire up VE.Configure - was that the issue? Do I need to install the Lithium Assistant. This issue is 3yrs old - hoping the new VE.Connect deals with it. Also I'm on MacOS - going to dust off a PC and try also.
