June 15, 20206 yr I am thinking of changing the settings of my Axpert inverter so that it can charge my lithium ion batteries at very low current (say 2 Amps) at night. Will the batteries go bad as a result?

But I can't see any reason to charge them slowly. As long as the charge settings (e.g. bulk/absorb voltage) are correct, and as long as you stay below the manufacturer's recommended maximum charge current (usually C/2), there should not be any problem. Using very high charge voltages (such as the Pylontech recommended charge voltage of 53.2 V for 15S LFP) can cause issues, but charging at 2 A maximum may not help with that problem anyway.
